TESTO 770-2 – CLAMP METER 0590 7702
The TESTO 770-2 clamp meter is designed for use in hard-to-reach places where wires are positioned close together. Its innovative design features a movable jaw that can be fully retracted into the housing, allowing for easy clamping of individual wires and precise measurements.
The TESTO 770-2 model offers advanced measurement functions, including the ability to measure inrush current, ionization current in microamperes, as well as temperature (using an external type K thermocouple probe). It is a reliable tool for the daily work of service technicians, electricians, and HVAC professionals.
The device automatically detects the type of current—AC or DC—eliminating the need for manual mode switching. The TRMS function ensures accurate readings even with non-standard signal shapes, and the ability to measure additional parameters such as resistance, continuity, capacitance, or perform a diode test enhances the meter’s versatility.
A backlit, dual-line display ensures readability in all lighting conditions. With the type K thermocouple adapter, the TESTO 770-2 gains an additional temperature measurement function, making it an exceptionally versatile tool for professionals.
