The ultimate kit for air conditioning, refrigeration and heating contractors, enabling the measurement of temperature, humidity, flow and pressure. In conjunction with a smartphone or tablet, the refrigeration kit is ideally suited to servicing and troubleshooting on air conditioning, refrigeration and heating systems, as well as their installation. All the measuring instruments can be quickly and easily commissioned and attached directly at the pressure connection or the temperature measuring point. They also make it considerably easier to work on measuring points that are a long distance apart, thanks to wireless connection to a smartphone or tablet and a range of up to 350 ft. (testo 549i, testo 115i, testo 605i).

The measuring values of both instruments are transmitted via Bluetooth® connection to the App installed on the smartphone/tablet enabling convenient and flexible readout. In the App, measurement parameters can be deleted, added or their order altered with just one click. It is also possible to change the displayed measurement parameters just as quickly. All measurement data are presented either as a diagram or a table. Finally, the measurement data report can be e-mailed directly as a pdf or Excel file.
