testo 770-3 - Hook clamp and power meter with Bluetooth

0590 7703
  • Unique hook-on function separates and grabs wires, without using your hands, and the retractable post makes hook release in tight spaces fast and easy
  • Bluetooth, coupled with the free testo Smart Probes app, works with smartphones and tablets for remote viewing, data logging, and report creation
  • Real-time power measurements (Watts), with simultaneous power factor indication  
  • μA parameter for flame rod (ignition flame sensor) testing, and temperature measurement using optional type K thermocouple adapter
  • The testo 770-3, in addition to the features of the other meters in the testo 770 series, includes real-time power measurements (Watts), power factor, and Bluetooth. The Testo app can be used for remote viewing, monitoring, data logging, and creating reports. This powerful app allows you to create custom reports that include photos, data, and graphs that can be saved, or sent via email.
    The testo 770 series identifies the testing in-process and automatically selects the correct meter configuration, which saves you time and increases your accuracy.

    The testo 770 series of instruments is rich in the features HVAC techs need and want, including TRMS, starting current, and frequency measurement.
