Martindale PSI4000 Phase Rotation Tester, CAT III 1000 V, CAT IV 600 V, 65Hz Max, 1000V ac Max with RS Calibration

The Martindale PSI4000 is a unique phase rotation indicator that carries out the measurement via 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.
The design of this phase rotation tester allows for use on both insulated or uninsulated conductors, and an "Enhanced Brightness" switch makes indication brighter in strong ambient light. A combination of both rotating LEDs and buzzer tones indicate clockwise or anti-clockwise rotation

4 x AA batteries, soft carry case and instruction manual

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.
