    Martindale VT12/PD Voltage Indicator and Proving Unit Kit

    The Martindale VT12/PD Voltage Indicator and Proving Unit Kit is a handy bundle for checking that electrical circuits are safely isolated before starting work on them. It consists of the Martindale VT12 Voltage Indicator, the Martindale PD690 Proving Unit and a useful carry case.

    The Martindale VT12 Voltage Indicator is a two-pole voltage detector capable of sensing AC/DC voltage from 12V to 690V. It has a handy LED bar-graph display which shows nominal voltage level at 12V, 24V, 50V, 120V, 230V and 690V. All the user needs to do is insert the poles into the voltage source and the tester will automatically indicate any potential.

    In addition to standard voltage detection, the Martindale VT12 can perform a continuity test up to 500kΩ and a single-pole phase test. The rugged construction and ergonomic design makes it comfortable to use and sturdy enough to withstand the challenges of regular use.

    A useful proving unit is provided alongside the voltage tester in order to allow the user to verify the performance of the tester before and after any work. The Martindale PD690 provides a known 700V output in order to check the indicator throughout its entire range.

    A useful carry case is also provided with separate compartments for the two individual instruments. It has padded shoulder strap and a special flap allows the PD690 to be used without being taken out of the case.
