The Testo 755-2 belongs to Testo's family of current and voltage testers. These are the first of their kind: voltage testers that meet the latest standards and can also measure current. Therefore, it is suitable for nearly all daily electrical measurement tasks. In every application, it automatically selects the correct settings, preventing dangerous misconfigurations. The device features all the essential functions for detecting voltage/voltage absence, measuring current and resistance, as well as for continuity testing. Additionally, the integrated flashlight allows for illuminating dark areas. The test probes can be easily replaced, so the entire device does not need to be replaced in case of damage. Furthermore, the Testo 755-2 has a wide voltage range of up to 1000 V, single-pole phase testing, and rotational field measurement.
