Los 5 mejores multímetros de circuito en Estados Unidos 2026: opciones clave para 2026

Build quality is excellent. The red rubber holster is thick and properly fitted. The tilting bail on the back doubles as a hanger and is sturdy enough to support the meter's weight. The rotary switch has precise detents and a satisfying mechanical feel.

The included silicone test leads are notably better than what ships with most meters in this price range. They are soft, flexible, and rated for the full CAT IV 1000V.

The 60000-count display is the spec that first grabs attention. In high-resolution DCV mode, the BM869s actually pushes to 500000 counts (0.1 microvolt resolution on the 500mV range), which is resolution you would expect from a bench multimeter costing $500+.

Accuracy is where the BM869s separates from the competition. The 0.025% basic DCV accuracy embarrasses the Fluke 117's 0.5% and the UT61E+'s 0.1%.

The dual display is more than a gimmick. You can simultaneously show VAC and Hz, DC and AC components, temperature differential (T1-T2), or current and frequency.

Safety is independently verified CAT IV 600V / CAT III 1000V with 12kV transient protection. EEVblog forum users have noted this is among the safest handheld meters available at any price under $400.

The BM869s supports PC connectivity via an optional optical USB cable (BU-86X), which is a separate purchase. The included Windows software is functional if dated, capturing measurements and supporting basic logging.

The VFD mode deserves special mention. It applies a low-pass filter and displays both the fundamental voltage and frequency of variable frequency drive outputs -- a genuinely useful feature for industrial electricians that most competing meters lack.

Precision bench work is where the BM869s justifies its existence. Calibrating voltage references, measuring op-amp offset voltages, characterizing low-noise power supplies, and logging temperature drift all benefit from the high resolution and accuracy.

Industrial electrical work benefits from the CAT IV rating and VFD mode. Troubleshooting motor drives, checking three-phase power, and verifying control voltage are all within scope.

Power supply development and repair is another sweet spot. The dual display lets you watch DC output voltage and AC ripple component simultaneously without switching modes. The crest (peak) capture helps identify transient spikes that average readings would miss.

In addition to this, it has a fast continuity mode with a clear, latching beep. Fluke is really the only other manufacturer that has a handle on super-fast continuity checks, but you’re paying for the pleasure.

Along with Max/Min and average mode – seeing high, low and their average in a signal – there is also crest, hold and relative modes. The record feature allows you to data log to an extent and then send the data over to a PC with the extra USB cable.

The main feature of the Brymen BM869 is definitely its display. It can measure to 500,000 counts in DC mode, or 50,000 counts in normal mode. The backlight is especially impressive, albeit it turns itself off after a few seconds to preserve the battery.

The sampling/refresh rate is up to five times a second – or 1.25 times a second in 500,000-count mode – with the super-responsive bar graph up to 60 times per second. This makes it great for picking up even minute fluctuations in a signal, much like a good analog meter would.

It has an auto shut-off to help save the battery. This kicks in after around 15 minutes of non-use. Also of use is the Beep-JackTM warning system, which beeps and puts ‘InEr’ on the display if you have the leas plugged into the wrong inputs with a given range switch setting.

This is a CAT-IV-rated meter to 1000V, which is an excellent rating and gives it an overload/surge protection of 12kV. This is thus an industrial strength meter, able to measure systems at source and everything behind it, including switch gear.
