The compact UNI-T voltage tester is a reliable tool for electricians and DIYers. It offers automatic AC/DC detection, LED indication of voltage and polarity, a warning for hazardous voltages above 50 V, and a durable design with IP54 rating. No batteries required – it is powered by the measured voltage, so it is always ready to work.
Automatic AC/DC detection and polarity
The device automatically recognizes AC or DC voltage and indicates DC polarity (+/−) using clear LEDs.
Bright LED indication from 12–400 V
Segmented LEDs display individual voltage levels for quick and safe reading even in challenging conditions.
Durable IP54 design with no batteries required
IP54 rating, 2 m drop resistance, and power from the measured circuit ensure reliability and readiness anytime.
Looking for a simple yet robust tester to quickly verify the presence of voltage? UNI-T provides clear LED indicators for 12–400 V AC/DC ranges, automatically detects the voltage type, and clearly shows polarity for DC. The integrated over-50 V warning enhances safety at work.
Thanks to IP54 protection, resistance to 2 m drops, and power drawn directly from the tested circuit, this tester is ideal for both workshop and field use. No batteries, no hassle – a reliable helper for quick diagnostics of outlets, distribution boards, and appliances.
