The Testo AC & Refrigeration test and load kit includes two Testo 549i high-pressure measuring instruments, two Testo 605i thermohygrometers and two Testo 115i clamp thermometers for pressure, (air) temperature and humidity measurement. In conjunction with a smartphone or tablet, the kit is ideally suited to servicing and troubleshooting on air conditioning and refrigeration systems, as well as their installation. The Testo 549i and Testo 115i can be quickly and easily 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.

The measuring values of both instruments are transmitted via Bluetooth to the Testo Smart Probes App installed on your terminal device enabling convenient and flexible readout there. In addition, the App enables automatic calculation of evaporation and condensation temperatures as well as of heating/cooling output. 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.
