Clamp Meter - testo 770-1
Model No: testo 770-1 Part No: 0590 7701

Testo 770-1 clamp meter is ideally suited for non-contact current measurement on tightly packed power cables or conductors with a small diameter. The unique grab mechanism means you can grab each individual cable easily and safely

  1. Fully retractable pincer arm for maximum flexibility
  2. Auto AC/DC
  3. Large two-line display
  4. Measures the common electrical parameters


This clamp meter means you can cope in any application environment, no matter how tight. The movable pincer arm can be fully retracted into the instrument, so that you can for instance grab tightly packed cables in switching cabinets as if you were using a hook. You have never been able to measure as conveniently as this in tight spots.

The operation of the testo 770-1 clamp meter is also easier and more reliable than ever before. It automatically detects and selects AC/DC and other electrical parameters, such as resistance, continuity, diode and capacitance. In addition, you can also use it to measure the starting current. And the two-line display presents your readings clearly and distinctly

Digital Clamp Meter - testo 770-2
Model No: testo 770-2 Part No: 0590 7702

Testo 770-2 the perfect clamp meter for non-contact measurements on tightly packed cables with a small diameter. In addition to the standard functions of the testo 770-1 clamp meter, it also offers a temperature adapter and measures current in the µA range

  1. Fully retractable pincer arm to make your work easy
  2. Auto AC/DC and large two-line display
  3. Measuring functions for starting current on electric motors and μA measurements
  4. Temperature adapter for type K thermocouples


Testo 770-2 clamp meter makes it so much easier to work on tight measuring points, such as switching cabinets. The clamp meter's movable pincer arm can be fully retracted into the instrument. This means you can accurately grab tightly packed conductors such as cables and check them for faults.

Furthermore, it enables measurement of the starting current on electric motors and ionisation current testing in the µA range. The supplied 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 meter detects and selects AC/DC fully automatically and also provides automated selection of other electrical parameters such as resistance, continuity, diode and capacitance. This makes operation easier and more reliable than ever before. Your readings are clearly and distinctly presented on the two-line display
