The EZ150 is the first socket tester that checks the wiring of 13A sockets and also gives a measurement of the earth loop impedance.
Conventional socket testers have the weakness that they only confirm that the earth is connected but they don’t indicate how safe it is. A socket with a dangerously high earth resistance could be passed as safe when using a standard check plug.

Martindale’s T-Safe™ patented technology gives safe, earth loop impedance checking within carefully selected bands, without tripping RCDs and RCBOs.

The EZ150 is an “advanced socket tester” as described by the Health & safety Executive.
