BFKK Digital Multimeter 8-100V 100A

This digital multimeter measures DC voltage from 8 to 100 volts and current up to 100 amps. It suits owners of 12V, 24V, 36V, 48V and 60V battery systems in automotive, RV, boat and solar installations. The meter tracks capacity up to 99999AH and power up to 50KW. It is not for users who need AC measurement or data logging beyond the on-screen readouts.

Voltage accuracy ±1% + 2 digits current precision

The instrument samples twenty times per second across a voltage range of 8-100V and a current range of 0.05-100A. Accuracy is stated as ±1% plus two digits for voltage and ±0.5% plus two digits for current. Readings update at that fixed rate, so rapidly changing loads are captured within the stated precision. Buyers who require laboratory-grade resolution or faster sampling should look elsewhere.

2.4 inch colour LCD with adjustable backlight

A 2.4 inch colour LCD provides high-contrast visibility in sunlight or darkness, with ten brightness levels and an auto-off timer. The display board measures 86 by 53 by 17 millimetres and the measuring board 56 by 36 by 34 millimetres. A supplied base allows stable panel or bench mounting. Users who need a handheld form factor without a fixed mount may find the base unnecessary.

Questions about this item

Should I pick a unit rated for 12 V, 24 V, 36 V, 48 V or 60 V systems?

One meter covers the whole 8–100 V range, so it works on 12 V, 24 V, 36 V, 48 V and 60 V installations without needing a different model.

What does the 100 A current rating mean when I wire this into my RV or solar battery bank?

It measures discharge or charge currents from 0.05 A up to 100 A continuously, showing real‑time amps, watts and accumulated amp‑hours on the colour LCD.

How does the 20‑times‑per‑second sampling rate affect the readings I see on the 2.4‑inch display?

The display refreshes 20 times per second, giving near‑instant voltage, current, power and capacity updates even during rapid load changes.
