When properly specified, socket testers provide a fast and effective solution to identify potentially unsafe installations and wiring faults.

They can be particularly useful as a service tool for identifying potentially unsafe conditions prior to installing new plant and equipment. Clearly socket testers are not an alternative to the full verification of wiring installations, however as a first line indicator they are an essential tool for all maintenance teams.

Single Phase Industrial Socket Testers

The CP Series of industrial socket testers from Martindale includes both 230V and 110V models.

Martindale CP201 230V single phase industrial socket tester

The Martindale CP201 is an industrial version of the classic check plug, fitted with a 250V 16A plug (BS 4343 / IEC309) and capable of identifying 28 fault conditions.

Wiring faults are instantly indicated by one or more of the LEDs failing to illuminate, with the pattern of lit LEDs indicating the type of fault detected. There is a look up chart on the tester for quick fault diagnosis.

Martindale CP301 110V single phase industrial socket tester

The Martindale CP301 is suitable for checking industrial sockets on 110V centre tapped circuits. It is fitted with a yellow 110V 16A CT plug to BS 4343/IEC309 and uses 3 bright LEDs to provide fail-safe fault indication with an on-tester look up chart for fast and simple fault diagnosis.

Fault indications include Line 1, Line 2 and centre tap faults, plus Line 1 or 2 centre tap reversal.
