Testo 770-2 TRMS Clamp Meter with Temperature Measurement

What is the Testo 770-2 TRMS Clamp Meter?

The Testo 770-2 is a True RMS AC/DC clamp meter designed for electricians, HVAC engineers and maintenance technicians. Its retractable pincer arm makes it easier to grip individual conductors in crowded switch cabinets and confined electrical installations.

 

Electrical, Microamp and Temperature Measurement

The Testo 770-2 measures AC/DC current up to 400A and voltage up to 600V, plus resistance, frequency and capacitance. It also measures microamps and temperature using a Type K thermocouple, making it particularly useful for electrical and HVAC diagnostics.

 

How does the Testo 770-2 stand out in everyday use?

Automatic measurement parameter recognition helps simplify testing while True RMS, starting current measurement and the 32mm retractable clamp provide practical functionality for everyday fault finding.
