Simple and Reliable Socket Safety Checker
The CP501 Classic Check socket tester is a handy tool for quickly checking the safety of your 240V sockets. It’s very straightforward to use—just plug it in and the indicator lights clearly show whether the wiring is correct or if there’s a fault. This makes it ideal for both DIY users and anyone wanting extra peace of mind at home.The compact design is easy to carry around, so you can test multiple sockets without hassle. The light indicators are bright and easy to understand once you’ve checked the guide. It feels solid enough for regular use and doesn’t require any setup or batteries.It’s especially useful for identifying common wiring issues quickly, though it’s more of a basic diagnostic tool rather than a full electrical tester. Overall, a simple, effective, and affordable device for checking socket safety.

A Classic Tester which works very well
Martindale testers have been around for decades, are simple to use and reliable. I quickly found out some of my sockets had live and neutral reversed - so much for professional installers!!

Brilliant plug

Does all you need it to.
Perfect for work as an electrician. Always bemuses me though the price for the sake of a buzzer compared to those without. Only reason it’s not 5 stars.
