The Martindale PSI3000 is the ultimate phase sequence (rotation) indicator. It combines an easy to follow rotating disc with fault indicators showing if any of the phases are down. The disc continues to rotate after disconnection, giving more time to identify the phase sequence.

A velcro strap allows the unit to be attached to conduits etc. which leaves hands free to use the test leads. The PSI3000 incorporates Martindale’s safety fused fixed-shroud leads for full compliance with GS38 and BSEN 61010.

Three easy to fit crocodile clips are supplied as standard.

The PS13000 with clockwise rotation disc is illustrated – for anti-clockwise indication of correct rotation specify the PSI3300.
