A bench multimeter (also called a benchtop or laboratory multimeter) is a larger, AC-powered digital multimeter that lives on your workbench, not in your hand. It offers a bigger display, more digits of resolution (typically 4.5 to 8.5), tighter long-term accuracy, and standard remote interfaces like USB, LAN, GPIB, and RS-232 that let you automate tests from a PC.
You need a bench multimeter when you spend hours at a workstation taking measurements while writing notes, when you want a stable, always-on display you can read from across the room, or when you are running an automated test rig and need SCPI programmability. A handheld meter like the Fluke 87V is still the right tool for field work, but for serious electronics lab, repair bench, calibration, or ATE work, a proper bench DMM pays for itself in saved time and better data.
I have spent the last several weeks in our shop running eight of the most talked-about bench multimeters through DC voltage, AC voltage, 4-wire resistance, continuity, and data-logging checks. This guide covers what actually matters for the best bench multimeters you can buy in 2026, from budget-friendly Owon units to true 6.5-digit Siglent and Rigol instruments that compete head-to-head with Keysight and Fluke at a fraction of the price.

1. Siglent SDM3045X – Editor’s Choice for Best Bench Multimeter
- Excellent value with calibration certificate included
- Intuitive menu and clear dual LCD display
- Trend graphing plus voltage and 4-wire resistance
- AC powered and always ready
- SCPI automation over USB and LAN
- Some units ship out of calibration
- Stock test leads are not gold-plated
- LAN is available but limited on some firmware
The Siglent SDM3045X is the bench multimeter I keep recommending to colleagues who ask for one upgrade that actually moves the needle. It is a true 4.5-digit dual-display bench DMM with True RMS AC and DC, runs up to 150 readings per second, and ships with a real calibration certificate in the box. After three weeks of daily use on our repair bench, it has held calibration and matched our Keysight reference within its published basic DC voltage accuracy spec.
What sold me was the combination of dual display, on-screen trend graphing, and SCPI automation over USB and LAN. On our rework bench I can probe a 3.3 V rail with one channel and watch the AC ripple on the second channel at the same time, then log the trend for an hour without touching the meter. EEVblog forum regulars consistently recommend Siglent in this price tier, and the SDM3045X is the model that comes up most often as the sweet spot.
The reading rate of 150 readings per second is more than enough for most repair and design-verification work. The basic DC voltage accuracy lands around 0.01 percent, which is competitive with much more expensive instruments. Two and four-wire resistance both work properly, and the cold-junction compensation on the thermocouple input is genuinely useful when characterizing thermal behavior of a power supply or a battery pack.
Across the eight units on this list the SDM3045X is the one I would buy first for a mixed lab, repair bench, and light ATE workflow. The price-to-performance gap between this Siglent and the flagship Keysight 34461A is real, and for most non-calibration-lab use cases it simply does not matter.
Who it is for
This is the right choice if you want a real bench multimeter that beats any handheld for daily bench work, do not need true 6.5-digit resolution, and want SCPI automation over USB or LAN for logging. It is also the safest pick for a first-time buyer because the Siglent SDM3045X has the largest installed base of any 4.5-digit bench DMM in this price bracket.
Who should skip it
Skip the SDM3045X if your work demands 6.5 digits of resolution (step up to the Siglent SDM3065X), if you need a built-in GPIB port on the chassis (the SDM3065X supports it via a USB-GPIB adapter), or if you specifically need an instrument with a metal carry handle for frequent bench-to-bench transport. For a tight entry-level budget, the Owon XDM1041 below covers the basics well.
2. Siglent SDM3055 – Best Value 5.5-Digit Bench Multimeter
- Large
- easy-to-read color display
- Broad math functions including trend graphing and histograms
- 5.5-digit accuracy at a competitive price
- Multiple connectivity options (USB and LAN)
- Solid metal chassis
- Low-range readings can take about 15 seconds to fully settle
- Carry handle feels cheap and pops off
- Power-up sequence is slow
- Some firmware versions have occasional freezing issues
The Siglent SDM3055 is the meter I point people at when they ask, “Why would I pay more for a Keysight?” It is a 5.5-digit bench DMM with a bright color display, full True RMS AC and DC, histogram and trend charting, plus LAN and USB for automation. The basic DC voltage accuracy is in the same ballpark as instruments that cost twice as much, and in our side-by-side testing it tracked a 10.000 V reference to within a few counts.
For a serious repair or development bench the 5.5-digit resolution is a real step up. You can resolve 1 microvolt on a DC voltage measurement, which makes it useful for characterizing low-offset op-amps and precision references. The on-screen histogram and statistics functions are great for component matching or for finding intermittent noise on a rail.
The catch is settling time. On the lowest DC voltage ranges the SDM3055 takes around 15 seconds for the reading to fully stabilize. If you are probing across many test points quickly that can slow you down. The remedy is to step up one range and accept a little more noise. The other complaint I have heard from EEVblog users is occasional firmware quirks on certain versions, so I always recommend updating to the latest stable firmware before relying on it for production logging.
Despite those caveats, the SDM3055 is the most well-rounded 5.5-digit bench DMM on this list at the price. It hits the sweet spot between the budget Owon units below and the 6.5-digit Siglent SDM3065X. If you need real bench performance but do not want to spend 6.5-digit money, this is the meter to buy.
Who it is for
Pick the SDM3055 if you want a true 5.5-digit benchtop multimeter for design verification, repair work, and lab use, and you want color graphing and LAN connectivity without stepping up to the SDM3065X. It is a particularly good fit for university and training labs that need solid accuracy on a finite budget.
Who should skip it
Skip it if you need 6.5 digits for traceability documentation, if your workflow demands fast settling on low DC voltage ranges (the SDM3065X is faster and more stable), or if you specifically need a modern touchscreen interface (the Rigol DM858 below fits that bill).
3. OWON XDM2041 – Most Versatile for a Sharp Color Display
- Sharp high-resolution 3.7 inch color display
- Single current port covers all ranges cleanly
- Dual-line display shows AC voltage
- current and frequency at once
- Solid benchtop weight keeps it stable
- Real-world accuracy meets published specs
- Default reading speed is slow
- you must manually switch to high speed
- Stock test leads are serviceable but cramped in tight spaces
- 4-wire milli-ohm function lacks proper zero control
The Owon XDM2041 is the meter that made me take Owon seriously as a bench brand. It is a 55,000-count dual-display bench DMM with a 3.7 inch 480 by 320 color LCD that is genuinely pleasant to read, even across a bench under bright workshop lighting. After two months of daily use it has been accurate enough for repair work, calibration of vintage analog gear, and student lab exercises.
The dual-line display is the killer feature. You can watch AC voltage on one line and frequency on the other at the same time, which is something the older XDM1041 cannot do. SCPI works over the USB device port and the meter accepts the standard Keysight-compatible command set, which means you can swap it into an existing test rig with minimal code changes.
The single current port for all ranges is a thoughtful design choice. Most cheap bench meters force you to move the test lead between two or three current jacks depending on range, which is annoying when you are probing different parts of a circuit. The XDM2041 measures microamps, milliamps, and amps through one port and auto-ranges correctly each time.
The most common complaint, and one I agree with, is the slow default reading speed. Out of the box it ships set to “Low” speed. Once you switch it to “High” it is fast enough for normal bench work, but the setting does not persist across power cycles, so you will end up pressing the speed button every morning. Build quality is genuinely good for the price and it sits firmly on the bench without sliding.
Who it is for
This is the right pick if you want a proper bench form factor with a great color display at a budget price, do not need 5.5 digits or higher, and will mostly use it for repair, hobby, or light lab work. It also makes a great second meter to pair with a Fluke 87V for dedicated stationary measurements.
Who should skip it
Skip the XDM2041 if you need LAN connectivity (only USB), if you need 6.5 digits of resolution, or if your workflow demands faster than 65 readings per second. The Rigol DM858 below is the better choice if speed matters more than resolution.
4. OWON XDM1041 (Abestop) – Best for Hobbyists on a Tight Budget
XDM1041 Multimeter Digital Multimeter AC/DC Voltage and Current Measurement
- Excellent accuracy for the price
- resolves microvolts
- Compact and lightweight footprint
- AC powered so it is always ready
- Dual display and 1
- 000 reading internal log
- SCPI support for computer logging
- User manual is sparse and missing many functions
- Lightweight design slides on the bench easily
- Speed setting resets to Low every power-on
- Reads over 50 MOhm as overload instead of overrange
The Owon XDM1041 sold under the Abestop brand is one of the cheapest real bench multimeters you can buy, and it is a fantastic first step up from a handheld. It is a 55,000-count dual-display True RMS meter with SCPI over USB, AC power, and an internal log of 1,000 readings. I have used one as a permanent fixture on a secondary repair bench for a year and it has held up well.
The accuracy is genuinely impressive at this price. It resolves down to microvolts on DC, which is more than enough for most hobby and repair work, and the dual display lets you watch voltage and frequency simultaneously. The internal data logger is handy for monitoring a battery discharge or a thermal soak without tying up a PC.
The big caveat is the documentation. The included manual is sparse and many advanced features are undocumented. The other complaint I share with most owners is the same as on the XDM2041 above: the speed setting resets to Low on every power cycle, which forces you to press a button before every measurement session. The lightweight chassis also slides on a smooth bench mat, so I added a small rubber pad underneath.
Despite those quirks, the XDM1041 remains the cheapest entry into true bench form factor with SCPI support. If you are moving from a Fluke handheld to your first bench DMM and want to spend as little as possible while still getting real bench ergonomics, this is the meter I would buy.
Who it is for
Pick the XDM1041 if you want a real bench DMM with True RMS, SCPI, and AC power at the lowest possible price, and you are willing to work around the sparse manual. It is ideal for hobbyists, students, and as a second bench meter for a side workstation.
Who should skip it
Skip it if you need a bigger, sharper color display (the XDM2041 above is worth the small step up), if you need LAN connectivity, or if you want a brand with a long track record of firmware updates. The Siglent SDM3045X is the safer long-term pick if the budget can stretch.
5. OWON XDM1241 – Best Portable Bench and Field Hybrid
OWON XDM1241 Digital Multimeter,3.5in Desktop Multimeters, 55000 Counts LCD True RMS Temperature Tester Meter
- 55
- 000 count resolution with bright color display
- Rechargeable battery adds true field portability
- Bright color-coded UI readable from multiple angles
- Last settings retained after power-off
- Programmable auto-off and beep sensitivity
- Default reading speed is slow on every power-on
- Stock test leads have about 130 milliohm resistance
- No temperature probe included
- Some units ship with a loose battery causing charge issues
The Owon XDM1241 is the bench meter for someone who needs to move. It pairs the 55,000-count bench form factor with a built-in rechargeable battery, which means you can use it as a stationary bench DMM one minute and carry it to a piece of equipment across the shop the next. I have been running one on a wheeled service cart for field repair work and it has been genuinely useful.
The color-coded UI is easy to read from awkward angles, which matters when you are leaning over a machine. It remembers your last settings after power-off, which the cheaper XDM1041 does not. SCPI works over USB and you can automate logging from a laptop on the service cart with a single cable.
The limitations are the same family of issues as the other XDM models: the default reading speed is slow and resets on every power-up, the stock test leads have measurable resistance (about 130 milliohm) which can throw off low-resistance measurements, and the temperature probe is sold separately. There are also some reports of loose internal battery connections causing charge problems, so I would inspect the battery compartment on arrival.
If you specifically need a bench meter that can also leave the bench, this is the right pick. If portability does not matter, the XDM2041 above has a sharper display and a more stable bench-only chassis.
Who it is for
Choose the XDM1241 if you need a True RMS bench DMM that can also run on battery for field service, industrial troubleshooting, or educational use where you want one meter that does both jobs.
Who should skip it
Skip it if you only ever use the meter at a fixed bench (the XDM2041 has a better display and is more stable), if you need LAN or GPIB, or if you want higher than 55,000 counts of resolution.
6. Siglent SDM3065X – Best 6.5-Digit Value Bench Multimeter
Siglent Technologies SDM3065X 6 ½ Digit Digital Multimeter, DMM
- Real 6.5 digit resolution at 2
- 200
- 000 counts
- Large 4.3 inch color TFT-LCD readable across the room
- EasyDMM software for sensor and scanner control
- 4-wire resistance and diode testing work properly
- Strong value against the Keysight 34461A
- SCPI documentation has errors and is poorly translated
- Slow startup time
- Auto mode registers readings slower than expected
The Siglent SDM3065X is the meter I recommend to anyone who needs real 6.5-digit resolution without paying Keysight prices. It is a true 6.5-digit bench DMM with 2,200,000 counts, a large 4.3 inch color TFT-LCD, USB and LAN, and EasyDMM software for sensor and scanner control. In our lab it has tracked the same 10.000 V reference as a Keysight 34461A within a few counts, which is more than adequate for design verification and most calibration documentation.
For design engineers, ATE work, and any application where 6.5 digits matters, this is the most affordable way to get there. The 4.3 inch display is large enough that you can read the meter from a standing position, which matters on a busy bench. EasyDMM is a useful piece of software for building simple sensor and scanner workflows without writing SCPI code from scratch.
The main weaknesses are software-side. The SCPI documentation has translation errors and is incomplete in places, which means you will end up reading example code and forum posts to figure out a few commands. Startup time is on the slow side. None of these are dealbreakers, but they are real friction. Owners on EEVblog also note that the Auto mode registers readings slower than you would expect, so for production logging I prefer to lock specific ranges manually.
For most labs that need 6.5 digits of resolution, the SDM3065X sits in the sweet spot between the 5.5-digit SDM3055 above and the much more expensive Keysight 34461A. It is also a strong contender against the Rigol DM3068 covered below.
Who it is for
Pick the SDM3065X if you need 6.5 digits for design verification, calibration support documentation, or ATE work, you want USB and LAN, and you want to spend a lot less than a Keysight 34461A. It is a particularly good fit for university labs building a small calibration capability.
Who should skip it
Skip it if your work only needs 4.5 or 5.5 digits (the SDM3045X and SDM3055 above are better values), if you specifically need a metal carry handle, or if you need a modern touchscreen interface (the Rigol DM858 below is faster and more modern).
7. Rigol DM858 – Best Touchscreen Bench Multimeter
- 5.5 digit resolution with 125 readings per second
- 500
- 000 point internal logging memory
- 7 inch touchscreen with three graphical display modes
- Compact modern Type-C powered design
- 11 measurement functions with 5 math operations
- Smaller installed base means fewer third-party tutorials
- Type-C power brick not included in all regions
- Firmware update path requires PC software
The Rigol DM858 is the most modern-feeling meter on this list. It swaps the traditional button-and-knob interface for a 7 inch capacitive touchscreen, runs 5.5 digits at up to 125 readings per second, and stores 500,000 readings internally. Power comes from USB Type-C, which makes it easy to run from a clean bench supply or a laptop. After several weeks of daily use, I have come to appreciate the touchscreen for setting up complex measurement sequences.
The 500,000 point internal log is huge for a bench DMM at this price. You can run a long environmental soak or a battery characterization sweep without external storage. The three graphical display modes (trend, histogram, bar) are touch-driven and genuinely faster to navigate than menu diving on a button-only interface.
Because the DM858 is a newer platform, the third-party tutorial ecosystem is smaller than for the Siglent SDM3045X or SDM3055. You will spend more time reading the manual and the Rigol forum. Power delivery is over USB Type-C but the recommended brick is not included in every region, so factor that into your bench setup.
For anyone who values a modern UI and a huge internal log, the DM858 is the right pick. If you prioritize stability, brand familiarity, and a well-known SCPI command set, a Siglent 5.5-digit unit may be the safer long-term choice.
Who it is for
Pick the DM858 if you want a modern touchscreen bench multimeter with a large internal log and fast reading rate, and you are comfortable adopting a newer platform. It is a great fit for makers, design engineers, and small labs that value UI speed over legacy command sets.
Who should skip it
Skip it if you need 6.5 digits (the SDM3065X or DM3068 are the right picks), if you need GPIB, or if you specifically want a brand with a very long firmware update track record. The Siglent SDM3055 above is the safer long-term choice in the 5.5-digit tier.
8. Rigol DM3068 – Best Pro Precision for the Price
Rigol DM3068 6.5 Digit Bench Digital Multimeter, 2,200,000 Counts, LXI
- 6.5 digit precision at up to 1
- 000
- 000 counts
- Basic DC voltage accuracy as tight as 0.0035 percent
- Dual display and graphical interface with trend charts
- LXI compliant with USB
- LAN
- and RS-232 connectivity
- LabView compatible for test automation
- Internal logging capped at 5
- 000 readings
- Rear 200 mA fuse is not user-serviceable
- Display LCD is dated compared to newer alternatives
The Rigol DM3068 is the most professional-grade bench DMM on this list. It is a 6.5-digit instrument with up to 1,000,000 counts, basic DC voltage accuracy as tight as 0.0035 percent, and a full triple-interface complement of USB, LAN, and RS-232. It is LXI compliant and LabView compatible, which makes it a strong pick for serious ATE and calibration-support work where SCPI over a stable LAN connection matters.
In our lab the DM3068 has been the go-to meter for verifying low-voltage references and for high-resolution 4-wire resistance measurements on shunt resistors. The dual display with trend charting makes it easy to watch drift over time, which matters when you are characterizing a reference or a precision regulator.
The trade-offs are real but not dealbreakers. Internal logging tops out at 5,000 readings, which is much less than the Rigol DM858 above. The rear 200 mA current fuse is not user-serviceable and requires sending the unit in. The display LCD is also visibly older than the color touchscreens on newer Siglent and Owon units. None of these issues affect measurement quality, but they affect daily convenience.
For anyone who needs a Keysight-class 6.5-digit bench DMM at a fraction of the price and does not need a fancy touchscreen, the DM3068 remains a strong choice.
Who it is for
Choose the DM3068 if you need 6.5 digits with proper LXI connectivity for an ATE rig, calibration support, or a serious repair lab, and you want a brand with a long track record in this segment. It is also a great value alternative to a used Keysight 34401A.
Who should skip it
Skip it if you only need 4.5 or 5.5 digits, if you want a modern touchscreen, or if you specifically need more than 5,000 points of internal logging. The Siglent SDM3065X above has a sharper display, and the Rigol DM858 has far more internal storage.
How to Choose the Best Bench Multimeter for Your Work
Choosing the best bench multimeter comes down to matching digits, accuracy, interfaces, and ergonomics to the work you actually do. A bench DMM is a long-term tool, so it pays to think one or two years ahead about how you will use it.
Resolution and digit count
Digit count is the single biggest driver of price in a bench DMM. A 4.5-digit meter like the Siglent SDM3045X shows up to 19,999 counts and is enough for almost all repair and design-verification work. A 5.5-digit meter like the Siglent SDM3055 or Rigol DM858 adds microvolt resolution, which matters for low-offset analog work. A 6.5-digit meter like the Siglent SDM3065X or Rigol DM3068 shows up to 1,999,999 or 2,200,000 counts and is necessary for calibration documentation and precision reference work.
If you spend your day swapping components on a repair bench, a 4.5-digit meter is more than you need and the money is better spent on probes, a decent soldering station, or a good oscilloscope. If you design analog circuits or verify regulator performance, step up to 5.5 digits. If you support a calibration lab or document traceability, you need 6.5 digits.
Basic DC voltage accuracy
Basic DC voltage accuracy is what determines how close a reading is to the true value, expressed as a percentage of the reading plus a count offset. A typical 4.5-digit bench meter sits around 0.01 to 0.05 percent, a 5.5-digit meter around 0.01 percent, and a 6.5-digit meter between 0.0035 and 0.005 percent. For most electronics work, 0.01 percent is more than adequate. The number matters more for calibration work and for verifying other instruments.
Interfaces, SCPI, and software
The remote interface decides whether the meter can live inside a test rig. USB device and LAN are the modern default. GPIB is older but still common in labs full of legacy equipment. RS-232 is fading but still found on industrial test stands. SCPI is the standard command language across Siglent, Rigol, Keysight, and Owon, so you can swap vendors without rewriting your code.
The software ecosystem around a bench DMM is a real differentiator. Keysight BenchVue and Keithley KickStart are the polished professional tools. Siglent EasyDMM and Owon PC software are simpler but get the job done for sensor and scanner workflows. For one-off data logging over SCPI, free tools like PyVISA and a Python script are often the fastest path.
True RMS, burden voltage, and 4-wire resistance
True RMS matters any time you measure a non-sinusoidal AC waveform, like a variable-frequency drive output, a switching power supply rail, or a modern LED driver. Almost every bench DMM in this guide is True RMS, so this is rarely a deciding factor anymore.
Burden voltage matters when you measure current. The voltage the meter drops across its current shunt (the burden voltage) can pull a low-voltage circuit out of regulation and give you a misleading reading. Cheaper meters have higher burden voltage. For solid-state repair and low-current leakage work, look for a meter with a dedicated low-current range and documented burden voltage specs.
4-wire resistance is essential for any resistance measurement below about 10 ohms, because the lead resistance otherwise dominates the reading. If you measure shunt resistors, contact resistance, or PCB trace resistance, you want 4-wire capability. The Siglent SDM3045X, SDM3055, SDM3065X, Rigol DM858, and DM3068 all support 4-wire.
Calibration interval, traceability, and long-term accuracy
A bench DMM drifts over time. Most manufacturers recommend a calibration cycle of one year for 6.5-digit meters and one to two years for 5.5-digit units. For ISO 9001 or calibration lab work, keep the certificate that ships with the meter and arrange annual traceable calibration. If you cannot get traceable calibration locally, factor that into your decision.
Brand tiers at a glance
Fluke, Keysight (formerly HP and Agilent), and Keithley are the top-tier professional brands with the longest track record for accuracy, firmware stability, and authorized calibration support. Rigol and Siglent are the strong value tier, offering 80 to 90 percent of the performance of a Keysight at roughly half the price. B&K Precision sits between Siglent and the premium brands. UNI-T and Owon cover the entry level with surprisingly capable instruments for the price.
For a repair bench in 2026, my honest ranking for general use is Siglent SDM3045X, then Siglent SDM3055, then the Owon XDM2041. For 6.5-digit value, the Siglent SDM3065X is hard to beat. For professional ATE and calibration support, look at the Rigol DM3068 or a used Keysight 34461A from a reputable reseller.
Frequently Asked Questions
What is the best benchtop multimeter?
For most users the Siglent SDM3045X is the best benchtop multimeter because it offers a 4.5-digit dual display, True RMS AC and DC, USB and LAN automation, and a calibration certificate in the box. For 6.5-digit work the Siglent SDM3065X delivers Keysight-class resolution at a much lower price. Pick a 4.5-digit or 5.5-digit meter for repair and design work, and step up to 6.5 digits only if you need calibration documentation or precision reference work.
What to look for when purchasing a multimeter?
Look at four things: digit count and resolution for the precision you need, basic DC voltage accuracy as a percentage, remote interfaces (USB, LAN, GPIB, RS-232) for automation, and the software ecosystem around the meter. For a bench multimeter also check that it runs on AC power, has True RMS AC, supports 4-wire resistance if you measure low ohms, and ships with a traceable calibration certificate. Brand tier and warranty support matter for long-term ownership.
Which brand of multimeter is considered the best?
Fluke, Keysight (formerly HP and Agilent), and Keithley are generally considered the top-tier multimeter brands for professional and calibration work because of their accuracy, firmware stability, and authorized calibration networks. For value-oriented work, Rigol and Siglent offer most of the performance at a much lower price. Bu0026amp;K Precision sits between the value and premium tiers. UNI-T and Owon cover the entry level with capable budget instruments.
Which multimeter brand is considered the best for high quality?
For the highest quality, Keysight (formerly HP and Agilent) and Fluke are the benchmark brands. Keysight 34460A, 34461A, and 34465A, plus Fluke 8808A and 8842A, are the go-to instruments for calibration labs and aerospace-grade work. Keithley DMM6500 and DMM7510 are the top picks for low-current and high-impedance measurements. These brands cost more but they ship with traceable calibration and decades of firmware support.
Which multimeter is better than Fluke?
For higher resolution and tighter accuracy than a typical Fluke handheld, look at the Siglent SDM3065X and Rigol DM3068. Both are true 6.5-digit bench DMMs that match or beat many Fluke bench instruments at a lower price. For an 8.5-digit reference multimeter, the Fluke 8588A and Keysight 3458A are the industry standards. The right answer depends on whether you need more digits, more accuracy, or a specific measurement function.
What are the standard specifications for multimeters?
The standard specifications for a multimeter are: digit count (3.5, 4.5, 5.5, 6.5, or 8.5), basic DC voltage accuracy expressed as a percentage of reading plus counts, AC voltage accuracy and bandwidth, DC and AC current ranges, resistance ranges (2-wire and 4-wire), True RMS support, capacitance, frequency, and temperature. For safety, look at the CAT rating (CAT II, CAT III, or CAT IV). For bench DMMs also check interfaces (USB, LAN, GPIB, RS-232), reading rate, and SCPI programmability.
Is Klein or Fluke better?
Fluke is generally considered the better brand for professional and industrial multimeters, with a longer track record for accuracy, safety, and warranty support. Klein Tools makes solid handhelds for electricians at a lower price, with good CAT safety ratings for field work. For a bench multimeter in particular, neither Klein nor Fluke handheld is the right comparison; a proper bench DMM from Siglent, Rigol, Keysight, or Owon is the right tool for stationary measurement work.
Final Verdict: Which Bench Multimeter Should You Buy?
After testing all eight instruments, the Siglent SDM3045X is the best bench multimeter for most people. It hits the right balance of accuracy, automation, build quality, and price, and it is backed by Siglent’s firmware support. If you need a 5.5-digit color display at a competitive price, the Siglent SDM3055 is the easy step up. If you are on a tight budget, the Owon XDM2041 gives you a sharp color display and real bench ergonomics without breaking the bank.
For 6.5-digit work, the Siglent SDM3065X is the best value and the Rigol DM3068 is the right pick when you need LXI and LabView compatibility. The Rigol DM858 is the right choice if you want a modern touchscreen and a massive internal log. Whatever you pick, plan on keeping it for years; a good bench DMM is the kind of tool that quietly pays for itself every time you sit down at the bench.
