Testo manufacture a range of current measuring instruments. The most popular of these is our testo 770 Clamp Meter series, of which there are three versions. The testo 770-1 is the standard model, ideal for most daily measurements. The testo 770-2 has the advantage of a &micro;A range, plus an integrated temperature adapter for all type-K thermocouples. In addition to all the features listed above, the testo 770-3 Clamp Meter has Bluetooth, meaning it can be connected to the testo Smart App and other testo instruments, giving you a more sophisticated performance measuring function. In the App for example, you can view the measurement progression in graph form and document it directly as a report. 
 
Testo&#39;s 770 Clamp Meter has a fully retractable pincer, meaning cables can be grabbed and isolated with ease. Much like Testo&rsquo;s range of Multimeters, our clamp meters also have an &#39;automatic parameter detection&#39; function. With this innovative feature, measurement parameters are detected automatically, leaving no room for error and ensuring your peace of mind. All Testo 770 Clamp Meters detect both direct and alternating current, and automatically select other parameters such as continuity, resistance, diode and capacitance.
