Martindale Phase Sequence Indicator

The Martindale phase sequence indicator works on a principle of static induction with voltage rating ranges between 150V and 1000V AC (phase to earth). It includes 4xAA batteries, a soft carry case and instruction manual. This indicator measures inductive crocodile clips. This method increases the safety of the user, whilst the bright LEDs give a clear indication of either clockwise or anti-clockwise phase rotation.

Supplied with

4 x AA batteries, soft carry case and instruction manual
