Testo 755 range | Current / voltage testers

Contact Instrument Solutions

The Testo 755 range of testers meet the latest standards for voltage measurements and are also able to measure current to make them suitable for virtually all daily electrical measuring tasks. The convenient open-jaw current tester automatically turns on when voltage exceeds 6 V. Each time you use these instruments they automatically select the right settings preventing dangerous use. The models also have all the important functions for measuring current and resistance, determining voltage / de-energisation and continuity tests. They also have an integrated torch which enables work in poorly lit spaces.

The Testo 755-2 includes additional features such as single pole phase testing and rotating magnetic field measurement, phase rotation and also a larger voltage measuring range of up to 1000 V.
