Description
Kewtech KT1790 Voltage Detector
Easy to use, with integrated GS38 slender probe tips and a range of useful testing functions, the Kewtech KT1790 Voltage Detector is a two-pole voltage tester that makes a perfect addition to a professionals’ instruments.
Capable of carrying out all necessary voltage testing procedures, including AC/DC voltage tests to 690V, continuity, single pole phase testing, phase rotation and indication of polarity, the KT1790 voltage tester uses both LED indicators on a scale and shows full test values on a built-in LCD screen.
Working in darkened environments? A built-in torch light will help you see in the dark and keep testing safely. The KT1790 is also capable of easily fitting inside recessed terminals such as RCBOs without unscrewing the caps, making life easier for the user.
This voltage tester is designed in compliance with IEC 61243-3 and IEC 61010-1 and is CAT IV 600V rated.
