Clamp meter testo 770-2

The testo 770-2 clamp meter (also known as a clamp meter) makes it much easier to work in tight measurement areas, such as switchboards. The fully retractable jaw design makes it easy to check wiring for faults in tight spaces such as switchboards.

Furthermore, it allows measuring the starting current on electric motors and checking currents in the µA range. Besides measuring electrical parameters, a Temperature Adapter is provided for connecting thermocouple probes (these compatible TC type K probes can be optionally ordered).

The testo 770-2 clamp meter also detects and selects AC/DC currents fully automatically. In addition, the testo 770-2 automatically selects other electrical parameters such as resistance, continuity, diode and capacitance. These features make electrical testing easier and more reliable than ever. Your measurement results will be clearly displayed on the display (2 lines).

Provide cover:testo 770-2 TRMS, batteries, 1 set of measuring cables (0590 0010), 1 x adapter for thermocouple type K, user manual.
