The testo 750-3 voltage tester is the most innovative voltmeter on the market. The clear all-round LED display with fibre-optic technology for ideal voltage indication can easily be read in any position. A second LC display also indicates the current reading. An anti-slip ring and the ergonomic shape of the handle also ensure you can work comfortably. The integrated torch helps with the illumination of dark measuring points. And the voltage tester is extremely durable thanks to the robust housing. 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.
