Feature
Fully retractable pincer arm to make your work easy
Auto AC/DC and large two-line display
Measuring functions for starting current on electric motors and μA measurements
Temperature adapter for type K thermocouples
The innovative grab mechanism makes the testo 770-2 the perfect clamp meter for non-contact measurements on tightly packed cables with a small diameter. In addition to the standard functions of the testo 770-1 clamp meter, it also offers a temperature adapter and measures current in the µA range.
