This is the first socket tester that gives a measurement of the earth loop impedance. This is the only safe solution for socket testing, as other testers can indicate as “safe” a socket with a dangerously high earth resistance.
Conventional indicators have the weakness that they only tell if the earth is connected, they don’t indicate how safe it is. Martindale’s new T-Safe™ patented technology gives safe, earth loop impedance checking within carefully selected bands, without tripping the RCDs.
- Non-trip earth loop test
- Voltage test
- Socket test for open termination and correct wires
- T-Safe™ patented technology
- Identifies faults other checkers can’t
