Description Technical Info Reviews Accessories

A combination testing device, Martindale VT25 can be used to evaluate levels of voltage, continuity and also gives indication of three phase rotation.

The Martindale VT25 is a dual pole tester and uses LED indication to showcase measurements when applied to the measurement point. It can be used to measure both AC and DC voltage levels up to 690V, includes a built-in continuity test with audible and visual indication and also includes resistance levels of up to 500kΩ.

Working in darkened conditions? The VT25 includes a built-in LED torch, allowing the user to easily see where connection points are in darkened panels or other similar applications.

This voltage indicator is CAT IV 600V and CAT III 690V rated.
