Martindale Buzz Socket Tester
Safe and simple to use, the BUZZ-IT (BZ101) is a real improvement for awkward sockets.
Thanks to the new BUZZ-IT, there’s no more need for scrambling around, twisting your neck trying to see the lights.
It has an audible signal to tell you instantly whether or not the wiring is correct and can also be used as a fuse finder - the correct fuse is located when the buzzer stops!
If there is a problem the pattern of neon lights indicates the fault, similar to the Classic Check Plug.

Any result other than 3 indicators lit and a continuous buzzing tone shows a fault condition.

Xtra Non-Trip Earth Loop Impedance Indicator
Identifies faults other checkers can’t !

A revolutionary new socket tester with earth safety test, voltage and wiring checks. Conventional socket testers have the weakness that they only tell you if the earth is connected, they don’t tell you how safe it is. Martindale’s new T-Safe™ Technology gives safe earth loop impedance checking within carefully selected bands without tripping the RCDs.
