testo 549i – wireless sensor for absolute pressure

The practical pressure sensor testo 549i is part of the 2nd generation of the testo SmartProbes series with, among other things, up to 100 m Bluetooth range. It is used in combination with a smartphone or tablet. It is suitable for servicing, troubleshooting and installing cooling and heat pump systems.

The sensor can be quickly and easily connected directly to the pressure connection, thanks to the 45° angle. When working with pressure connections that are far apart, the testo 549i makes work much easier – thanks to the wireless transmission of measurement data to a smartphone or tablet. Since no hoses are needed for the measurements, the loss of refrigerant is minimal.

More convenient measurement thanks to the app

The user can conveniently read the measured values in the free app downloaded to a smartphone or tablet. In combination with the pipe temperature sensor testo 115i, individual system parameters such as e.g. overheating is also calculated. The app also enables automatic calculation of evaporating and condensing temperatures.

All measurement data are presented either as a graph or in tabular form. Measurement results can then be sent directly as PDF or Excel files.

Included in delivery

The testo 549i is delivered with batteries and factory protocols.
