The best multimeters for electronics are the Brymen BM235 for most bench and repair work, the Fluke 117 for dependable general-purpose troubleshooting, and the Rigol DM3058E when you need bench-meter resolution rather than portability.
The right choice depends less on the largest advertised digit count than on how the meter behaves around real circuits: whether it settles quickly, reports small changes consistently, detects continuity without an irritating delay, and survives an accidental connection to the wrong voltage. Capacitance and frequency ranges are useful extras, but probe quality, input protection, and a predictable auto-ranging system often matter more.
Quick comparison: the leading choices

Published accuracy depends on temperature, measurement range, calibration interval, and the particular revision. Treat the figures above as buying comparisons rather than guaranteed results in every condition.
Best multimeter for most electronics work: Brymen BM235
The BM235 is a strong middle ground. Its 6,000-count display is detailed enough to show millivolt and resistance changes that a basic 2,000-count meter can hide, while its compact format fits beside a soldering station. It includes the functions electronics users commonly need: diode testing, capacitance, frequency, duty cycle, current ranges, and temperature support with the appropriate accessory.
Its main advantage is behavior rather than headline specifications. A good auto-ranging meter should move quickly from an unknown signal to a stable range without repeatedly jumping between ranges. The BM235 is generally well suited to checking power rails, resistors, switches, fuses, and assembled boards. Its continuity mode is also quick enough for tracing wiring without making you wait for every beep.
Look closely at the included leads before buying. Probe insulation, flexible silicone cable, sharp but replaceable tips, and a secure plug fit make repeated board work much less frustrating. If the package includes ordinary PVC leads, upgrading to silicone leads can be worthwhile even when the meter itself is excellent.
Best for dependable all-round use: Fluke 117
The Fluke 117 is an easier recommendation when the meter will move between electronics, household wiring, appliances, and service calls. Its LoZ mode helps reduce misleading “ghost” voltage readings on disconnected or capacitive conductors, while its input protection and physical construction are designed for demanding electrical work.
For low-voltage electronics, it is accurate enough for most troubleshooting but not the most informative choice for observing small changes on a 5 V rail or measuring a resistor near the edge of tolerance. The display is 6,000 counts, and the meter lacks some specialized conveniences found on electronics-focused instruments. Choose it for robust general use, not because it offers the highest resolution per dollar.
Best for harsh environments: Fluke 87V
The 87V earns its higher price through protection, accuracy, and features aimed at industrial equipment. Its low-pass filter can make variable-frequency-drive measurements more useful, and its temperature, capacitance, frequency, and min/max functions cover a broad troubleshooting workload.
For a hobbyist working only on battery-powered circuits, the 87V is usually excessive. For control cabinets, motor electronics, power supplies, and sites where a mistake can be expensive, the higher safety category and rugged design are more meaningful than a faster display or a few extra capacitance ranges.
Best budget high-resolution option: UNI-T UT61E+
The UT61E+ is attractive when display resolution matters and the budget is limited. Its 22,000-count readout can reveal finer changes than a typical 6,000-count handheld meter. That is useful when adjusting a regulated supply, comparing transistor junctions, or watching resistance drift as a component warms.
High resolution does not automatically mean high accuracy. A meter can display five digits while the last two are affected by noise, lead resistance, temperature, or calibration. The UT61E+ is best treated as a capable value instrument, with more attention paid to its current-fuse status, lead placement, and safety boundaries than you might give a premium meter.
Best when resolution and logging matter: Rigol DM3058E
A bench meter is the better answer when measurements are frequent, precise, and performed at one workstation. The DM3058E provides a 5½-digit display, more stable readings for supply and resistance work, and features such as statistics and data logging that are awkward on a handheld meter.
The trade-off is obvious: it needs mains power and bench space, and its continuity behavior is not optimized for rapidly probing a cable harness. Many electronics workbenches benefit from owning both a bench meter for reference measurements and a compact handheld meter for quick fault-finding.
How the important features affect your decision
Accuracy versus resolution
Resolution tells you how many display counts are available; accuracy tells you how close the result may be to the true value. For example, a 0.5% accuracy specification on a 12.00 V reading permits an error of approximately 0.06 V before adding display-resolution and temperature effects. If you need to distinguish 12.00 V from 12.03 V, choose a more accurate meter or verify the result with a calibrated reference.
Auto-ranging behavior
Auto-ranging is convenient for unknown circuits, but it can pause while the meter decides which range to use. A manual range is often quicker when repeatedly measuring 5 V logic, 12 V rails, or 10 kΩ resistors. Look for a meter with a clearly accessible range button and a reliable relative or zero function. Relative mode can remove probe resistance when measuring low resistances, but it cannot correct poor contact or a damaged fuse.
Continuity response
Fast continuity is one of the most valuable features for electronics repair. A delayed meter can make a good switch appear faulty or slow cable tracing. Audible thresholds vary, commonly activating below a few tens of ohms, so continuity is not a substitute for measuring the actual resistance. Keep the buzzer volume and response in mind if you work in a noisy workshop.
Capacitance and frequency
Capacitance measurement is useful for loose components and rough checks of electrolytic capacitors, but an in-circuit reading can be distorted by parallel components. Discharge capacitors first; even a small capacitor can damage the meter or produce an unstable result. Frequency mode is helpful for oscillators, PWM signals, and mains-derived waveforms, but check the specified frequency range and input amplitude. A basic multimeter measures frequency, not waveform quality or duty-cycle distortion; use an oscilloscope when signal shape matters.
Protection ratings and probe quality
CAT ratings describe intended transient environments, not permission to exceed every displayed range. Check the meter’s voltage and current limits, use the correct jack, and inspect the leads before each session. Fused current inputs are essential. Replace leads with cracked insulation, loose shrouds, or bent probe tips.
Decision matrix: which meter fits your situation?
| Your situation | Best fit | Why |
|---|---|---|
| Under $120, mostly low-voltage boards | UNI-T UT61E+ or Brymen BM235 | Useful resolution and electronics functions without bench-instrument cost |
| One meter for home, automotive, and electronics tasks | Fluke 117 | LoZ mode, strong protection, simple operation |
| Industrial controls or motor-drive troubleshooting | Fluke 87V | Higher accuracy, filtering, rugged construction, broader safety margin |
| Daily measurements at a dedicated workbench | Rigol DM3058E plus a handheld meter | Stable high-resolution readings and convenient logging, with portability covered separately |
Ownership details that affect long-term value
Test leads and probe tips usually wear before the meter does. Keep leads loosely coiled, avoid pulling on the plugs, and wipe flux residue from probe tips with appropriate electronics cleaner. Replace the battery when readings become erratic rather than assuming a circuit is faulty. Do not measure resistance, capacitance, or continuity on an energized circuit, and never leave a lead in the current jack when switching back to voltage measurements.
For most readers, buy the Brymen BM235 if electronics is the priority, the Fluke 117 if the meter must handle mixed electrical work, and the Fluke 87V if protection and industrial capability justify the cost. Choose the Rigol DM3058E only when a stationary, high-resolution instrument matches the way you work; otherwise, a responsive handheld with good probes will solve more everyday problems.
