Non-contact voltage tester Uni-T UT12E-EU

Uni-T UT12E-EU is a professional non-contact AC voltage tester that can detect voltages in the ranges of 24–1000 V and 90–1000 V at a frequency of 50/60 Hz. The device allows for quick and safe inspection of electrical installations without contact with wires, and thanks to IP67 protection and resistance to drops from a height of up to 2 meters, it performs well in demanding working conditions.

Accurate detection and convenient operation

The model offers two operating modes, allowing you to better adapt the operation to the type of installation. Audible and LED indicators make it easy to find live wires, while a built-in flashlight and vibration mode improve usability in dark and noisy environments. An auto-off function provides additional convenience.

Robust design for everyday use

The compact housing measuring 160.5 × 21.5 × 25 mm and weighing 72 g allows for comfortable use and easy portability of the device. High resistance to dust, water and drops increases the durability of the sensor during field work. It is a practical tool for electricians and service technicians who need fast and non-contact voltage detection.
