Clamp meter-Testo770-2
Features:
✔ Fully retractable pincer arm to make your work easy
✔ Auto AC/DC and large two-line display
✔ Measuring functions for starting current on electric motors and μA measurements
✔ Temperature adapter for type K thermocouples
The testo 770-2 is the ideal clamp metre for non-contact measurements on densely packed cables with a small diameter thanks to its unique grip mechanism. The Testo 770-1 clamp metre offers a temperature adaptor in addition to the normal features and measures current in the A range.
It is significantly simpler to operate on small measuring points, such as switching cabinets, with the Testo 770-2 clamp meter. The retractable pincer arm of the clamp meter has a full range of motion. This enables you to precisely grab densely packed conductors, like wires, and inspect them for flaws.
Testo 770-2 – Clamp meter also makes it possible to test ionization current in the A range and monitor the starting current on electric motors. Electrical parameters can also be measured using the thermocouple probe temperature adaptor that is included (a compatible type K thermocouple probe can be acquired separately).
Automatic detection and selection of various electrical parameters including resistance, continuity, diode, and capacitance are also offered by the clamp meter. Operation is now simpler and more dependable than before. Your readings are presented on the two-line display in a clear and distinct manner.
The 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.
