The three models in the testo 750 voltage tester family are the first instruments with an all-round LED display. The display can be seen from any position and guarantees an ideal voltage indication thanks to its unique fibre optics. All three models meet the latest voltage tester standard EN 61243-3:2010 and meet CAT III 1000 V CAT IV 600 V safety standards. They have the most important functions for voltage testing, continuity testing and rotating magnetic field measurement.The testo 750-2 is also suitable for single pole voltage testing and has a torch along with an RC trigger function. By applying a 35 mA load to the circuit, vibrating load buttons ensure that the trigger test cannot be carried out accidentally. In addition, the testo 750-3 is fitted with an LC display to show the current reading.
