The Kewtech KTP1 Proving Unit acts as a known voltage source for non-contact voltage testers before and after use. This is an essential part of the safe isolation process as it ensures that non-contact voltage detectors are functioning correctly and can therefore be relied upon.

The Kewtech KTP1 is compact and portable with a supplied 9V battery and a belt clip for hands-free use. A visual indication shows when it is being used and it can be activated just by pressing a single button. The robust design has been drop tested from a height of 1m.
