The Testo 770-2 true RMS clamp meter has signal detection capabilities that enables it to detect direct and alternating current and select other parameters such as resistance, continuity, diode and capacitance without interference by the user. With its unique fully retractable pincer arm, this allows you to grab wires without using your hands which makes it easier to take measurements in tight locations.

The Testo 770-2 model is ideal for daily measuring tasks such as frequency measurement, True RMS and current measurement. It also has a μA range as well as an integrated temperature adapter for Type K thermocouples.
