Martindale MARVIPD138-S Voltage Indicator & Proving Device

This voltage indicator and proving device from Martindale offers an instant, clear indication to show if a circuit is live, along with its voltage range, and whether AC or DC. Tough, moulded construction and LEDs, combined with heavy duty, double insulated cable, large finger guard and a retractable, lockable prod sheath make this the safest, most durable and reliable instrument of its type.

The PD440 proving device produces 440V AC/DC to enable voltage indicators and other devices with ranges up to 500V to be checked. It is a portable, battery powered proving unit with the option of being driven from a 12V supply via a car or mains power supply.

Suitable for: drummond test lamps, digital multimeters and low impedance voltage testers (LCD display).
