    Smart Phone + Smart Probes = Smart Work

    The handy high-pressure gauge testo 549i, in combination with a smartphone or tablet, is suitable for service and error detection on air conditioning and refrigeration systems, as well as for their installation. The measuring instrument can be quickly and easily attached directly to the pressure connection. When working at pressure connections which are far apart, the testo 549i makes the application considerably easier – thanks to a wireless connection to a smartphone or tablet. Also useful: since no hoses are needed for the measurements, very little or no refrigerant is lost.

    And if the clamp thermometer testo 115i is used simultaneously, individual refrigeration system parameters such as superheating can be calculated. Users can read off their measurement values comfortably in the testo Smart Probes App installed on the end device. The testo Smart Probes App additionally enables the automatic calculation of evaporation and condensation temperatures. All measurement data are presented either as a diagram or in tabular form. The measurement protocols can then be directly sent as PDF or Excel files.

    Testo Smart Probes App

    The App turns your smartphone/tablet into the display of the testo 549i.
