Description
Testo 770-3 True RMS Clamp Meter for HVAC
The Testo 770-3 is a True RMS clamp meter with a cable-grab jaw design built for demanding measurements in tight application environments — the kind of confined switchboards, condenser units and control panels that HVAC technicians work in daily. The slim jaw profile reaches conductors where standard clamp meters cannot, without sacrificing measurement accuracy.
Bluetooth connectivity enables wireless data logging to the Testo Smart App for on-site documentation. Non-contact voltage (NCV) detection adds a fast safety check before probing live circuits. See all electrical testing tools or browse the full test and measurement range at HVAC Shop AU.
