An upgraded version of Martindale's VT25 voltage indicator, this device includes all of the functions of that device but also includes an integrated LCD display which shows full test values as well as LED indication.

This device is used to give indication of voltage levels (both AC and DC) up to 690V, can be used to test continuity with audible and visual indicators and can also be used to give indications of three phase rotation.

A built-in LED torch on the end of the VT28 also ensures that it can be used in darkened conditions.
