Description

Safe electrical working requires the use of a voltage indicator that has been proven with a suitable proving device before and after use to ensure the instrument is working correctly in accordance with the Electricity at Work Regulations.

The PD440SRDX is fast and easy to use, instantly supplying the full test voltage for both high and low impedance voltage indicators, test lamps and meters. It comes complete with an over moulded low-profile case with magnetic hanger.

The PD440SRDX has a unique CALCHECK feature making it easy to verify the insulation and low resistance ranges on 18th Edition multifunction testers, wherever you are working.
