    Martindale PSI4000 Phase Sequence Indicator

    This Martindale PSI4000 Phase Sequence Indicator gives quick and easy indication of phase rotation via the use of three insulated crocodile clips which are attached to a measurement point.

    Phase rotation direction is shown via LED indicators on the front of the device which can be made brighter to be seen in different lighting conditions. It also uses audible tones to let the user know about whether rotation is clockwise or anti-clockwise.

    This tester can be used on insulated and uninsulated conductors.
