A revolutionary new earth loop indicator with voltage and wiring checks. Conventional indicators 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 RCD’s.

• Non-trip earth loop test
• Voltage test
• Socket test
• T-Safe technology
• Identifies faults other checkers can’t
