The Martindale CP301 is an industrial socket tester for instantly checking sockets on 110V centre tapped circuits. It is fitted with a yellow 110V 16A CT plug to BS 4343/IEC309 and provides similar fail-safe LED indication as 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.
