The testo 770 series identifies the testing in-process and automatically selects the correct meter configuration, which saves you time and increases your accuracy.

The testo 770 series of instruments is rich in the features HVAC techs need and want, including TRMS, starting current, and frequency measurement.

Testo’s history of efficiency, innovation, and quality now extends to the entire electrical lineup. Once again, Testo brings high value, feature-packed products to the HVAC contractor market.

In addition to the standard functions of the testo 770-1 hook clamp meter, the testo 770-2 includes a thermocouple adapter, and measures microamps.

Features:

Unique hook-on function separates and grabs wires, without using your hands
Retractable post makes hook release fast and easy
µA for flame rod (ignition flame sensor) testing, and can measure temperature using type K thermocouple adapter
