The Testo 750-3 is the highest spec voltage tester available in the Testo 750 series.

This is the only model in the series with dual voltage indication; the 750-3 includes both Testo's unique all-round LED voltage indicators (so you can see voltage levels even when holding the tester sideways or backwards) and is the only model in the 750 series with a built-in LCD screen to show an actual voltage measurement.

Every measurement function included on the 750-1 and 750-2 is included on the 750-3 as well. It can perform measurements of voltage, determine phase sequence, perform continuity tests, is suitable for single pole testing, has a built-in torch for use in darkened conditions and more.

The Testo 750-3 is ergonomically designed for a comfortable grip, with finger slip guards and recessed grip sections. It's also made with safety in mind and is IP64 rated, plus CAT IV 600V and CAT III 1000V rated.

Supplied as standard with a 2 year warranty from Testo.
