The testo 770-1 Clamp Meter is ideally suited for current measurement in switching cabinets. A major advantage of the testo 770 -1 is the fully retractable pincer. This unique mechanism means that cables in tight switching cabinets can be easily grabbed.

Another strong feature is the automatic measurement parameter detection. This ensures fast and reliable work: in the current and voltage area, all three versions of the clamp meter detect direct and alternating current and automatically select other parameters such as resistance, diode, capacitance, and continuity where applicable.

The testo 770-1 clamp meter is the standard version, perfect for the majority of daily measuring tasks, including starting current measurement.


Product advantages:

  • Unique grab mechanism makes it easier to work at tight measuring points
  • Auto AC/DC for current and voltage
  • Large two-line display
  • True root mean square measurement - TRMS
  • With additional functions, such as starting current, power and μA measurement
