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

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.
