The NC4 voltage tester has two sensitivity ranges for accurately detecting the presence of AC voltages. The first will detect voltages between 50V and 1000V and the second will indicate voltages between 12V and 1000V. Sensitivity can be set according to the application and when in high sensitivity mode the LED pulse double flashes.

The extended probe tip gives improved access and easier identification of live wiring. It indicates voltage by illuminating the clear tip section with a bright red LED and sounding a buzzer.

The pen-shaped design with clip makes it ideal for carrying in a pocket or tool belt when working at height or in difficult to access locations. There is a useful LED torch which illuminates the area directly in front of the tip. Auto power off and a recessed on button ensure a long battery lifetime and the NC4 functionality also includes low battery indication.

The NC4 replaces the Martindale VT4.
