Description
The Martindale CP301 is an industrial socket tester for instantly checking sockets on 110V centre tapped circuits.
It is fitted with a yellow 110V 32A CT plug to BS 4343/IEC309 and provides a similar fail-safe LED indication to the classic check plug.
Using LEDs to highlight possible fault combinations, the CP301 is invaluable for instantly checking sockets on industrial or site installations.
There is a look up chart on the tester for fast and simple fault diagnosis.
