Martindale PD440S Proving Unit 440V AC
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.
With all the benefits of the industry standard Martindale PD440 and PD690 proving units, the new S models come in an overmoulded low profile case with magnetic hanger. They are fast and easy to use, instantly supplying the full test voltage for both high and low impedance voltage indicators, test lamps and meters.
The SX Series have a unique CALCHECK feature making it easy to verify the insulation and low resistance ranges on 18th Edition multifunction testers, wherever you are working. In addition, the new SX models have stepped voltage LEDs with thresholds matched to most voltage indicators and two pole testers.
