It can be set up quickly and easily directly at the pressure connection point during maintenance, troubleshooting and installation. The testo 549i makes it easier to measure pressure connections at remote points. No hose is needed during measurement, reducing the loss of refrigerant caused by pipe connection. When wireless with testo 115iWhen the mini pipe clamp temperature measuring instrument is used in combination, it can also calculate the parameters of the refrigeration system. The testo Smart Probe APP provides higher measurement convenience. The measurement readings can be conveniently viewed on your terminal device through the testo Smart Probe APP. In addition, the testo Smart Probe APP can also be used to automatically calculate evaporation and condensation temperatures. All measurement data can be displayed in the form of graphs or tables.
