The NC1 is a non-contact magnetic field tester for checking the operation of relays and solenoid valves in a wide range of machinery. This feature saves time by allowing testing without having to dismantle the equipment or control panel. A bright yellow LED illuminates the clear tip of the tester and a buzzer sounds when a magnetic field is detected. Features and Benefits: LED torch allows use in low light Power on LED pulse and low battery indicator are easy to identify Extended probe allows access to hard to reach areas Clear tip allows for high visibility indication Tests solenoid valves and relays without dismantling Typical Applications: Electrical installations Electronic maintenance
