We offer a free of charge calibration and certification with the purchase of any of the Martindale test equipment range. In addition to detecting 28 socket wiring fault conditions and checking mains voltage levels, the EZ165 verifies the earth wiring by carrying out a non-trip earth loop test and indicating its value in 6 discrete ranges from less than 1. Martindale’s T-SafeTM patented technology gives safe earth loop impedance checking within carefully selected bands, without tripping RCDs and RCBOs.

Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above.They mention that it's simple to use, well made and a reliable tool for confirming the correct wiring in your home.

We are constantly striving to improve our service and are grateful to receive as much feedback as possible - good or bad. Used this handy device to test the sockets in a ring circuit before and after using Wago connectors and a blanking plate to decommission a redundant socket within the circuit. Advanced Socket Testers offer a simple solution to verifying socket earthing and are commonly used by engineers and technicians prior to servicing and installing mains powered electrical and gas appliances.

Zone D - Outer Hebrides, Orkney Isles, Shetland Isles, Isle of Man, Scilly Isles, and Channel Islands (Charges are calculated at the checkout). We are able to supply and support the full range of Martindale's Test Equipment, Including repairs and calibration. Great solution to match with the best range of lockout kits and separate devices available in the Reece range. Wiring faults are indicated by one or more of the LEDs failing to illuminate, with the pattern of lit LEDs indicating the type of fault detected.
