MARTINDALE ELECTRIC Socket Tester & Supply Polarity Checker

The Martindale Electric Socket Tester & Supply Polarity Checker is an essential diagnostic tool designed to detect 28 socket wiring fault conditions and check mains voltage levels. Crucially, it safely detects Line-Neutral reversal, also known as cross polarity, at the incoming supply.

This polarity swap test identifies a serious fault condition that standard socket testers cannot detect on PME/TN-C-S systems, which are the most common type of supply. The test is easily activated using the touch pad on the device. When correct polarity is confirmed, three flashing green LEDs provide a clear visual indication. If a fault condition is present, three red LEDs illuminate alongside a warning buzzer for immediate alert.

Featuring N, E, and L labelled LEDs, this socket tester quickly identifies the source of common faults, saving time during diagnostics. It also offers high and low voltage indications for comprehensive testing. The tough, sculpted design ensures easy removal from sockets, while the UK mains plug (Type G) makes it suitable for use in the UK, Ireland, Cyprus, Saudi Arabia, Malta, and many other regions.
