Description
Kewtech KT1780 Voltage Detector
Built specifically for the UK market, this two-pole Kewtech KT1780 Voltage Detector includes GS38 compliant probe tips and is a great tool quickly and easily evaluating overall voltage levels.
The main body of this tester features oversided LED indicators that show the presence of voltage (both AC/DC) up to a high point of 690V. The device can also be used to carry out continuity testing with clear audible tone, single pole phase testing, polarity indication, phase rotation testing and also performs a self diagnostic test to ensure efficiency at all times.
The 1780 is also built to be compliant with IEC 61243-3, IEC 61010-1 and CAT IV 600.V
