The NC3 is a non-contact voltage and magnetic field tester for accurately detecting the presence of AC voltages between 200V and 1000V. When voltages are detected, a bright red LED illuminates the clear tip of the NC3 and a buzzer sounds.

In addition to voltage detection, the NC3 can be used for testing relays and solenoid valves without having to fully dismantle the equipment. On detecting a magnetic field, a bright yellow LED illuminates the tip of the tester. Applications include troubleshooting and servicing of control equipment in process industries, energy, transportation and pneumatic and hydraulic control systems.

A built-in torch in the tip is ideal for use in low light areas clearly illuminating the area under test. Auto power off and a recessed on button ensure a long battery lifetime and the NC3 functionality also includes low battery indication.
