Best Multimeters for Electronics

For electronics bench work — continuity, resistance, diode and component checks, and small DC voltages — the Fluke 115 is the meter we'd put on many benches: True RMS, auto-ranging, a 6000-count display, and the capacitance, frequency, continuity and diode functions the job needs, rated CAT III 600V. Its current measurement starts at 6.000 A, so milliamp and microamp work is not its job. If your work includes small currents, the UNI-T UT61E+ brings a 22000-count display, a 0.01 µA current step and USB logging (confirm availability, because its global page currently says out of stock); the Fluke 179 is the mid-tier Fluke with temperature and 0.01 mA maximum current resolution; the Fluke 17B+ is the budget Fluke with fused microamp inputs; and the KAIWEETS HT118A is the value pick with the widest capacitance range here. All recommendations are based on manufacturer specifications and manuals, checked November 5, 2026; we have not tested these meters.

• 0.01 µASmallest DC current display step among these picks (UT61E+, per its manual)
• ±(0.05% + 5)UT61E+ DC voltage accuracy on its 2.2000 V through 220.00 V ranges
• 20 ΩFluke 115 continuity beeper threshold, on below this, per its spec table

Best overall: Fluke 115

Fluke's 115 page pitches the Fluke 115 Field Technicians Digital Multimeter at field service technicians: one-handed operation, a backlit 6,000-count display, and True-RMS measurement with AC and DC voltage, current, resistance, continuity, frequency and capacitance. That suits voltage and component checks, but not milliamp or microamp bench work.

• The bench functions: diode test (2.00 V range, 0.001 V resolution, 0.9% + 2 accuracy), continuity beeper on below 20 Ω and off above 250 Ω, resistance to 40 MΩ, capacitance to 9,999 µF at 1.9% + 2 from 100 µF to 1000 µF and 5% + 20 above that
• Voltage detail: 600.0 mV range at 0.1 mV resolution; DC volts specified to 0.5% + 2
• Current limits: AC/DC current to 10 A; the 20 A overload is allowed for 30 seconds maximum
• Safety: IEC 61010-2-033 CAT III 600V; 9 V battery, 400 hours typical without backlight; 3-year warranty; ships with a holster and 4 mm PVC-insulated test leads

The trade-off for electronics is the current section: the smallest range is 6.000 A, so there are no milliamp or microamp ranges for sleep-current or leakage work — Fluke's own product Q&A says the 110-series "doesn't have" small-current measurement and points buyers needing it to the 17B+, which it calls "more geared towards electronics." Its sibling, the Fluke 114, goes further: Fluke's page calls it a go/no-go troubleshooting tool, and it measures no current at all; it does add AutoVolt and a LoZ function for identifying ghost voltage. If you need microamps on a Fluke, skip to the 17B+ or 179 below.

Best resolution and logging: UNI-T UT61E+

The UT61E+ is the resolution pick. UNI-T's series page and its user manual document a 22000-count display and a 46-segment analog bar, against 6000 on the 115.

• Small currents: 220.00 µA and 2200.0 µA DC ranges, with 0.01 µA resolution on the lowest, specified to ±(0.5%+10); AC current accuracy is ±(0.8%+10) at 40 Hz–1 kHz and ±(3%+50) at 1 kHz–10 kHz
• DC voltage: 2.2000 V through 220.00 V ranges at ±(0.05%+5); the 220.00 mV range resolves 0.01 mV; input impedance about 1 GΩ on the mV range and about 10 MΩ on the others
• Component functions: resistance from 220.00 Ω to 220.00 MΩ, capacitance from 22.000 nF to 220.00 mF, diode test with about 3V open-circuit voltage and a normal forward drop between 0.12V and 2V, plus a transistor hFE socket (range 1000β, resolution 1β)
• Continuity: beeps below 50Ω conduction and stays silent at 70Ω or above
• Logging and modes: USB data transmission with maker-supplied software, relative (REL) zeroing, peak maximum/minimum capture; AC+DC and low-pass AC voltage modes
• Duty limits: when the measured current is above 5A, each measurement must be 10 seconds or less with 15 minutes of rest
• Protection: mA/µA input fused at 1A 240V, A input at 10A 240V (fast-acting, 6x25mm); CAT III 1000V / CAT IV 600V per the manual

The trade-offs are real: the global page says out of stock and unavailable, so confirm regional supply before planning around this meter. The largest capacitance range is only specified to ±(20%+5), and the manual gives no burden-voltage figure for the current ranges, so we make no low-burden claim. Our bench multimeter guide covers the step up to 5½-digit meters when 22000 counts is still not enough.

Best Fluke upgrade: Fluke 179

Fluke's 179 page calls it "the industry-standard troubleshooting tool for electrical and electronic systems," and its spec sheet is the strongest all-round set on this page.

• Accuracy and detail: DC volts ±(0.09% + 2) with 0.1 mV maximum resolution; DC current ±(1.0% + 3) with 0.01 mA maximum resolution; Fluke's comparison table lists microamps among the 179's measurement capabilities; analog bar graph and backlit display
• Ranges: voltage to 1000 V AC/DC, current to 10 A, resistance to 50 MΩ, capacitance to 10,000 µF at ±(1.2% + 2), frequency to 100 kHz at ±(0.1% + 1), temperature from -40°C to 400°C at ±(1.0% + 10)
• Safety and build: EN 61010-1 to 1000 V CAT III and to 600 V CAT IV; UL, CSA and TÜV listed; lifetime warranty; 420 g
• In the box: 80BK temperature probe, installed 9 V battery, test leads, quick reference guide

The trade-offs: a 9 V alkaline battery lasts about 200 hours typical without backlight — the shortest on this page — and the page does not state a display count. True RMS AC, temperature and Fluke's comparison-table microamps listing — with a specified maximum DC-current resolution of 0.01 mA — are why it costs more than the 115.

Best budget pick: Fluke 17B+

The 17B+ page is the cheapest way into a Fluke with the functions a bench needs: AC/DC voltage and current up to 1000 V and 10 A, resistance, capacitance and frequency checks, plus a supplied Type-K thermocouple. It is marked CAT III 600 V.

• Small currents: 400.0 µA and 4000 µA AC and DC ranges with 0.1 µA resolution, alongside 40.00 mA, 400.0 mA, 4.000 A and 10.00 A
• Accuracy: DC volts 0.5% + 3 from 4.000 V to 1000 V; DC current 1.5% + 3; frequency 0.1% + 3 from 10 Hz to 100 kHz
• Fuses: current inputs protected by 440 mA and 11A 1000 V fast fuses, Fluke-specified parts only
• Bench extras: relative zeroing for voltage-drop and temperature-change readings; diode test with typically 2.0 V open-circuit voltage and less than 0.6 mA short-circuit current; capacitance to 1000 µF
• Endurance and safety: 2 AA batteries with 500 hours minimum; IEC 61010-1 and IEC 61010-2-030 CAT III 600 V, Pollution Degree 2; 455 g
• In the box: meter, TL75 test leads, Type-K thermocouple probe, 2 AA batteries, users manual (part 4404231)

The trade-offs: 4000 counts rather than 6000 or 22000, diode accuracy is only specified to 10%, and the current page makes no True RMS claim. Buyers on a tighter budget should also see our budget multimeter guide.

Best value full-feature: KAIWEETS HT118A

The HT118A page packs the longest function list per dollar: auto-ranging, True RMS, non-contact voltage detection, live-wire detection, LED-lit input jacks, a flashlight, Min/Max/Average, and temperature.

• Ranges: DC voltage 600mV to 1000V and AC voltage to 750V in the spec table; DC and AC current 600uA/6000uA/60mA/600mA plus 10 A; resistance to 60 MΩ; capacitance from 10nF to 100mF; frequency to 10MHz; temperature -40°C to 1000°C
• Safety: IEC-rated CAT III 1000V / CAT IV 600V, CE and RoHS, with a double ceramic fuse and thermistor protection
• In the box: meter, test leads, thermocouple, two AAA batteries, user manual

The trade-offs we can verify: the feature text says "up to 600V" while the spec table lists ranges to 1000 V DC — KAIWEETS's own documents disagree, so confirm the maximum voltage in the supplied manual before relying on it. Capacitance accuracy is ±(4.0%+3), or ±(5.0%+3) on the 100mF range. There's no maker-stated continuity threshold or response time, so a fast beeper cannot be promised here.

Compare the small-current and component specs

• UNI-T UT61E+22000counts
• Fluke 1156000counts
• KAIWEETS HT118A6000counts
• Fluke 17B+4000counts

Source: each maker's page or manual, linked in the sections above (the Fluke 179 page states no count)

A big maximum-current number does not give you low-current detail. These are DC range and resolution specifications from the makers' documents, not our measurements:

Read the accuracy line next to every range: the UT61E+'s microamp ranges are ±(0.5%+10) and the 17B+'s are ±(1.5% + 3), so the finer display step is not automatically the more accurate reading. Current duty limits apply on the UT61E+ above 5A.

Read the CAT boundary before the feature count

Every meter here is safe for low-voltage bench work, and none of them should be your household-wiring meter by default. Fluke's multimeter safety guide places outlet and long branch circuits in CAT II, feeders and short branch circuits and devices fed directly from distribution panels in CAT III, and the service entrance, electricity meter and outside runs in CAT IV. Fluke's rule of thumb: choose a tool rated for the highest category you could potentially use it in.

The catch for electronics buyers: a CAT marking is about high-energy faults, not bench precision. A CAT III 1000V / CAT IV 600V marking like the UT61E+'s or HT118A's does not make the meter better at reading a diode — and a CAT III 600V marking like the 115's or 17B+'s covers outlets and branch circuits while leaving service-entrance work alone. The current-input fuses matter on the bench too: the UT61E+ protects its mA/µA input with a 1A 240V fast-acting fuse, a limit that has nothing to do with its 1000 V voltage ranges. Our electricians' multimeter guide covers mains-rated picks, and the parent roundup compares home, automotive and HVAC uses.

How we choose

We compared maker product pages, manuals and spec tables — display counts, smallest current ranges, accuracy lines, fuse ratings and marked CAT ratings — checked November 5, 2026. These are research-based recommendations; we have not physically tested any meter, and every figure here is the maker's own specification. Where a maker's documents conflict (KAIWEETS's maximum voltage, UNI-T's availability), we say so instead of picking the flattering number. Our selection method explains the process.

Buying guide: get the lead kit right too

1. 1

   List the smallest current you'll read

   Leakage, sleep draw and sensor bias need microamp ranges; component checks need diode test and capacitance.

2. 2

   Match resolution to accuracy

   A 0.01 µA step with ±(0.5%+10) accuracy is a display detail, not a precision promise; read both lines.

3. 3

   Check the current-input fuse and duty limits

   Fused microamp/milliamp inputs (17B+, UT61E+) and time-limited high-current ranges protect the meter and you.

4. 4

   Confirm the CAT boundary

   Bench work is low-energy; household mains needs a meter rated for that location and the leads to match.

Bench conveniences worth checking before ordering: a tilt stand or holster (the 115 ships with a holster; the HT118A has a stable kickstand and a back flashlight), jack lighting (the HT118A's LED lights on the jacks show the correct inputs), and relative zeroing (17B+ and UT61E+) for subtracting lead resistance. Replacement leads need the same 4 mm shrouded banana format the makers use — the 115 ships with 4 mm PVC-insulated test leads and the 17B+ with TL75 test leads. Our multimeter basics guide walks through the functions if this is your first meter, and the beginners' roundup covers gentler starter picks.

True RMS matters only where AC is distorted. On pure DC bench work it is irrelevant; Fluke's True RMS explainer notes an averaging meter can read distorted waves up to 40% low or 10% high, and recommends True RMS where AC characteristics are unknown.

Verdict

For most electronics benches the Fluke 115 is the sensible center: safe, readable, and complete for voltage, resistance, continuity, diode and capacitance work. Buy the UT61E+ when microamp resolution and logging drive the purchase (and after confirming availability), the 179 when you want Fluke accuracy with microamps and temperature in one meter, the 17B+ when the budget is tight but the inputs must still be fused, and the HT118A when function count per dollar wins. The parent best multimeters guide remains the starting point for mixed household use.
