Socket Testers

Our socket testers are an easy-to-use, safe, and cost-effective test instrument, and are an excellent way to troubleshoot the health of your electrical sockets. Using a socket tester ensures you have the necessary connections without risking electrocution or injury.

While all socket testers work on the same principle, there are different ways the information is displayed; some use audible signals to inform of incorrect wiring, while other types of socket testers use LED indicators to indicate wiring status. All of our socket testers and adaptors come with standard UK three-pin plug connectors as standard.

Our range of testers are available from brands such as Socket & See, Kewtech and Martindale, and include the brand-new Fluke ST240+ RCD Socket Tester! Prices starting from just £14.00 excl. VAT.
