A revolutionary new Martindale Ez150socket tester with earth safety test, voltage and wiring checks - Model MAREZ150. 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 on the Martindale Ez150.
