The KT1780 is a two-pole voltage and continuity tester used for safe isolation of live circuits. It indicates if voltage is present even with no batteries or if the batteries go flat, giving you peace of mind when working.

Bright LEDs light up behind the voltage indication to provide clarity even in dark spaces. It also fits into recessed terminals such as RCBOs without the need to unscrew caps.

• Oversize luminous LEDs – clearly displays voltage levels
• Dead battery indication – detects voltage even when batteries are flat
• Bright torch light – gives ample illumination in dark areas
• Phase rotation – shows left or right rotation with green LEDs
• Slim probe design – fits recessed terminals without unscrewing caps
