Xtra Non-Trip Earth Loop Impedance Indicator
Identifies faults other checkers can’t !

A revolutionary new socket tester with earth safety test, voltage and wiring checks. Conventional socket testers have the weakness that they only tell you if the earth is connected, they don’t tell you how safe it is. Martindale’s new T-Safe™ Technology gives safe earth loop impedance checking within carefully selected bands without tripping the RCDs.
