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 Martindale PD440S is a direct replacement for the industry standard PD440. Its voltage output is matched to the VI13800, the MTL10 and MTL20 Drummond test lamps and all other 440V voltage indicators and testers.

In addition to all the benefits of the industry standard Martindale PD440 and PD690 proving units, the S models feature a tough overmoulded low profile case and come with an MG3 magnetic hanger (excluding kits). They are fast and easy to use, instantly supplying the test voltage for both high and low impedance voltage indicators, test lamps and meters.

Essential for implementing effective safe isolation procedures.
Tough overmoulded low profile design.
Long battery life with low battery indicator.
Includes MAG3 high strength magnetic hanger.
Colour coded for voltage output.
