The 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.
Combined with a smartphone or tablet, the testo 115i clamp thermometer is the ideal temperature measuring instrument for carrying out servicing and troubleshooting on refrigeration, air conditioning and heating systems, as well as for installing them. It can also be used to measure flow and return temperatures.
