The traditional Martindale Socket tester identifies 28 different fault conditions via the super bright LED’s and key system in the instructions and is a must for everyone working with electricity. The MARCP520 has the same features with the added benefit of a 4mm earth connection for a banana plug to guarantee good earth.

The product has been developed in conjunction with the Telecoms and Broadband industries, where testing of the fibre optic network, using a Fibre Optic tester, is required and where accuracy depends on good earth.
