Martindale EZ165 Socket Tester 13A 230V ac CAT II 300 V

In addition to detecting 28 fault conditions and voltage level indication, the EZ165 shows how safe the earth wiring is by carrying out a non-trip earth loop test. A low earth resistance is essential for safety disconnection devices to work properly and prevent electrocution when faults occur.
