TIS PU1 – Reliable, Affordable, and Easy to Use

Essential TIS PU1 Proving Unit for All Voltage Testers 0 – 690V for Safe and Accurate Voltage Testing


The TIS PU1 proving unit is one of the most affordable and widely used voltage proving devices on the market today. It is a must-have tool for electricians, designed to verify the functionality of AC/DC voltage testers up to 690V. Commonly included in safe isolation kits, the PU1 ensures that voltage testers are working correctly before and after use, providing an extra layer of safety for professionals.

This user-friendly proving unit operates automatically, allowing electricians to quickly check voltage testers by simply pressing them against the unit’s connectors. When the voltage tester is functioning correctly, the PU1 will illuminate all LEDs and activate any acoustic tones for voltage and continuity indication. Additionally, a low battery warning LED ensures the unit is always ready for use.

Fully compliant with HSE GS38 regulations, the TIS PU1 is suitable for use with TIS voltage testers, including the TIS 859, TIS 849, TIS 851, and TIS 819, as well as other 2-pole voltage and continuity testers from various manufacturers.
