Testo 750-3 voltage tester is the most high-performance and most reliable voltage tester compared to the other models in the family. It not only features unique fiber-optic technology but also for single pole voltage testing. This testo voltage tester has the torch for measuring point illumination and the all-round LED display, it also has an LC display where the current values are being measured are displayed.
Applications: Test electrical circuits or systems for voltage or de-energization (according to DIN EN 61243-3:2010), Checking the rotating magnetic field, Single pole voltage testing to determine whether conductors are live, Checking RCD circuit breakers, Testing voltage supply in live wires.
