The Testo 770-3 Clamp Meter is the ideal for demanding measuring tasks in tight application environments and is the most powerful model in the clamp meter series. It offers a performance measurement function and can be connected via Bluetooth to the Testo Smart Probes App.

The clamp amperemeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode and capacitance. The movable pincer arm can be fully retracted into the instrument, enabling the instrument to grab tightly packed cables in a particularly accurate way.
