Overview
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.
The testo 745 Non-Contact Voltage (NCV) Tester quickly checks for the presence of voltage in AC powered systems. It can be safely used up to 1000 VAC. When AC voltage is detected, the testo 745 gives indication by flashing RED LEDs and buzzing audible tones. You can easily determine the hot and neutral legs of an outlet without lengthy and risky removal of the outlet. The testo 745 NCV has a built-in Low Pass Filter which greatly reduces high frequency interference which causes false indications. The included LED flashlight is bright and focused to make testing simple in dark spaces. It also includes a low battery indication and is waterproof and dustproof rated per IP 67. The testo 745 is rated to CAT III 1000V and CAT IV 600 V.
