Testo 770-2 Clamp Meter - 0590 7702
The innovative grab mechanism makes the 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.
The testo 770-2 cable-grabTM 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. In addition to electrical parameters, you can also measure temperatures with the integrated temperature adapter for type K thermocouples.
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.
