Martindale VT2 Non Contact Voltage Indicator Details
The Martindale VT2 is a pen-shaped voltage indication device that can alert the user to the presence of AC voltage from 200V up to 1000V (1kV).
Contact isn't necessary to detect voltage with this detector. Simply hold it near to a suspected voltage source and if voltage between the range specified is detected the tip of the pen will start to glow with red colouring.
Absolutely ideal for use by any electrical professional for testing walls, sockets, cables, circuit breakers and various other applications.
