The Testo 770-3 is the most advanced clamp meter in the Testo 770 series, engineered for demanding electrical measurement tasks in tight and complex environments. Its innovative retractable pincer arm allows effortless non-contact measurement—even on tightly packed cables—while its improved resolution enables highly accurate readings, especially in the lower current range.
With TRMS measurement, automatic AC/DC detection, and a large two-line LCD display, the testo 770-3 simplifies electrical diagnostics across HVAC, industrial, and commercial systems. Bluetooth® connectivity enables seamless integration with the testo Smart App and other Testo instruments, allowing measurement curves to be visualized, logged, and exported directly from a mobile device.
The 770-3 also supports starting current, power, μA measurements, capacitance, resistance, diode tests, continuity checks, and temperature measurement via an optional thermocouple adapter. Its robust design, extensive measurement functions, and smart connectivity make it a top-tier tool for professional technicians.
