Testo 770-2 Clamp meter

Order-Nr.  0590 7702

It is significantly simpler to operate on small measuring points, such as switching cabinets, with the Testo 770-2 clamp meter. The retractable pincer arm of the clamp meter has a full range of motion. This enables you to precisely grab densely packed conductors, like wires, and inspect them for flaws.

It also makes it possible to evaluate ionization current in the A range and monitor the beginning current on electric motors. Electrical parameters can also be measured using the included temperature adapter for thermocouple probes.

Automatic detection and selection of various electrical parameters including resistance, continuity, diode, and capacitance are also offered by the clamp meter. Operation is now simpler and more dependable than before. Your readings are presented on the two-line display in a clear and distinct manner.
