Martindale Buzz IT Socket Tester

Similar to the Martindale Classic Check Plug, the Buzz-IT Check Plug is a quick and easy way to see if 13A sockets are wired correctly. The major benefit of the Martindale Buzz-IT is an audible alarm which is sounded in addition to three illuminated neons to signify correct wiring. This is ideal for awkwardly placed or hard to see sockets.

The Martindale Buzz-IT Check Plug can also be used as a basic fuse finder – when the correct fuse is unplugged the buzzer stops.
