    Martindale VT28/PD Voltage Indicator and Proving Unit Kit

    The Martindale VT28/PD Voltage Indicator and Proving Unit Kit allows the user to detect voltage in circuits before he/she starts work, thus ensuring safe isolation during maintenance. It contains a feature-rich voltage detector, a 690V proving unit and a handy carry case.

    The Martindale VT28PD is a two-pole voltage indicator that can detect voltage presence from 12V to 690V AC/DC and then displays nominal voltage level in steps up to 690V (±12V, 24V, 50V, 120V, 230V, 400V & 690V). This makes it suitable for use in any EN61010 electrical installation. The vibrant LED display ensures that voltage presence and level are immediately apparent.

    Aside from simple voltage detection, the Martindale VT28 can also perform single pole phase testing, phase rotation testing and continuity testing so it is a versatile instrument. An inbuilt LED torch makes the tester ideal for use in the dark and the cable is double insulated to highlight damage.

    The Martindale PD690 included in the kit is an essential accompaniment to the voltage tester because of the need to verify a voltage detector before and after use. The unit produces a 700V test voltage which illuminates the unit’s entire LED display.

    Both the instruments in the Martindale VT28PD Kit are provided in a useful carry case with a handy shoulder strap.
