MARTINDALE VT25/PD LED VOLT TEST AND PROVING UNIT

Safe isolation procedures state that voltage indicators should be proved against a known source both before and after use. The VT25 is a two pole LED voltage indicator for use on AC or DC systems, displaying voltages from 12V to 690V. Additional functions of this model include audible and optical continuity, phase rotation and a single pole phase test. Safety features include a built-in torch, for working in darker areas and also two layers of insulation on the cable. The inner layer is a contrasting colour to the outer, making it easy to see if there has been any damage to the cable.
