testo 770-3 - Clamp meter with Bluetooth

0590 7703 02
  • Increased accuracy in the lower current range thanks to improved resolution
  • TRMS measurement
  • Auto AC/DC for current and voltage and large two-line display
  • Bluetooth connection to testo Smart App and other Testo measuring instruments
  • Easy to operate thanks to the retractable pincer arm
  • Non-contact measurement on tightly packed cables is really easy and reliable with the testo 770-3 clamp meter. Its innovative grab mechanism will make your work easy. The most powerful model in the clamp meter series, it offers lots of additional functions for those challenging tasks that you are faced with on a daily basis, e.g. connection to the testo Smart App and other Testo measuring instruments. Thanks to its increased resolution, the clamp meter delivers highly precise results even in the lower current range.

    The testo 770-3 clamp meter is the ideal clamp amperemeter for demanding measuring tasks in tight application environments. The movable pincer arm can be fully retracted into the instrument. This enables the instrument to grab tightly packed cables in a particularly accurate way.

    Thanks to improved resolution, high-precision results are also generated in the lower current range. The testo 770-3 also has an extended voltage measurement range of up to 1000 V.

    In addition, more specialized applications can be handled using the clamp meter, such as starting current, power and μA measurements. The optionally available temperature adapter for thermocouple probes can be used to measure electrical parameters as well as temperatures (compatible Type K thermocouple probe can be ordered separately).

    The clamp amperemeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode and capacitance,. This makes operation easier and more reliable than ever before.

    The measurement values can be clearly shown on the two-part display of the clamp meter and in the testo Smart App. The testo 770-3 can be quickly and easily connected to the testo Smart App and other Testo measuring instruments via Bluetooth. In the App, you can display the measurement curve as a graph on your smartphone/tablet and save and send readings directly in the report.
