Testo 770-2 TRMS Clamp Meter
The Testo 770-2 TRMS Clamp Meter is built for precision and simplicity in complex environments. With its fully retractable clamp arm, this meter easily accesses tightly packed cables in cabinets or control panels. It provides True RMS measurement, ensuring accurate readings even with non-linear loads.
Reliable Performance with Intelligent Functions
Designed to make your job easier, the Testo 770-2 automatically identifies the type of measurement and adjusts the settings accordingly. It handles AC and DC current up to 400 A and can measure voltage, resistance, capacitance, and frequency. The auto AC/DC detection and measurement parameter recognition reduce the risk of error and save time on-site.
Enhanced Versatility for HVAC Technicians
Alongside standard functions, the Testo 770-2 includes microamp (μA) current measurement for flame sensors and a temperature adapter for type K thermocouples. This makes it ideal for HVAC applications, where both electrical and temperature readings are needed. The compact design, large two-line display, and backlit screen ensure clear visibility even in low-light conditions.
This instrument combines safety, efficiency, and a high feature set. Whether you’re measuring inrush current, checking continuity, or logging temperature, the Testo 770-2 offers professional-grade performance in a durable, easy-to-use tool.
