Martindale VT7 LED Single Pole AC 50V – 600V Hazardous Voltage Indicator

Two year Martindale Warranty

Product Details

A single pole contact voltage indicator which detects AC voltages of 50V-600V with audible and bright LED indication.
This ergonomically designed voltage tester has a self-test function and is IP54 rated, for indoor and outdoor use.

The tester is of durable construction making it suitable for both industrial and utility applications.
The VT7 can be used when wearing protective gloves and gauntlets ensuring safe working practices can be adhered to at all times.
The probe is GS38 compliant and is ideal for detecting live panel casings.

An extended tip enables easy access in confined spaces.
The single pole contact design will detect potentially hazardous AC voltages under a wide range of operating conditions and is a useful
first line tool for detecting live voltages.

It is widely used by power utilities and other safety conscious organisations to reduce the safety risk from live panel casings and cutouts.
The VT7 is NOT suitable for proving dead, for this application a two pole voltage indicator should be used in accordance with safe isolation procedures.
