Testo 549i Smart Probe Refrigeration Pressure

The Testo 549i Smart Probe measures refrigerant charge pressures and wirelessly transmits data in real time to your phone or tablet. It can be used to check high-side or low-side pressure, or monitor both simultaneously if two instruments are used. The hose-free design uses far less refrigerant when servicing, and easily connects to standard Schrader valves. With two Testo 549i pressure probes plus two Testo 115i pipe-clamp temperature probes, you will have a wireless system that can check all pressures and temperatures and calculate superheat and sub-cooling.

The free Testo Smart Probes App is compatible with iOS 8.3 or newer and Android 4.3 or newer, and will support up to six Testo Smart Probes at a time. The app receives the measurements up to 60 feet away, and has multiple filtration and export features for reporting data. From live graphing, to building a full pdf report, the app has you covered. The 549i has a measurement range of -14 to 870 psi (-1 to 60 bar). The Testo 549i is also offered as a part of the Testo Refrigeration Smart Probe Set 


The Testo 549i comes with 2 Year Warranty.
