Description
The testo 750-3 voltage tester is the most high-performance model in Testo’s convenient and reliable voltage tester family. In addition to the unique fibre-optic technology, the single pole voltage testing, the torch for measuring point illumination and the all-round LED display, it also has an LC display where the value currently being measured is shown.
The testo 750-3 voltage tester is first and foremost suitable for determining voltage or de-energization on electrical circuits or systems. In addition, it can also be used to test continuity, measure rotating magnetic fields and test residual current circuit breakers via the RC trigger function. Vibrating load buttons ensure that trigger tests cannot be carried out accidentally.
Delivery Scope
testo 750-3 voltage tester, including batteries, measuring tip protector, measuring tip caps, calibration protocol and instruction manual.
