Martindale Buzz-It Check Plug & Sounder

This plug is a fast and easy way to ensure 13A sockets are wired correctly in the same way as the classic check plug. The Buzz It gives an audible signal in addition to the three LEDs lighting when the wiring is correct. This allows for awkwardly placed, or not easily visible, sockets to be checked quickly. It can also be used as a basic fuse finder. When the correct fuse is pulled the buzzer stops. The Buzz It shows 28 potential faults.
