0560 1549 01 549i Refrigeration Pressure Wireless Smart Probe by Testo

The testo 549i Smart Probe is a hose-less, wire-less, pressure probe for measuring refrigerant charge in AC/Refrigeration systems. It is used for servicing, troubleshooting, and documenting the operation of residential or commercial AC/refrigeration systems. When two 549i are used in conjunction with two 115i pipe-clamp temperature probes it is easy to monitor superheat and sub-cooling in AC/refrigeration systems. Users can read the measurements using the testo Smart Probes App installed on their smart device. The testo 549i easily connects to standard Schrader valves without tools and without hoses, eliminating any refrigerant loss. The testo 549i works on smart devices with either Android or Apple operating systems at distances up to 60'.

The testo Smart Probes App is a powerful and easy-touse tool. It allows you to remotely read measurements from up to six (6) Smart Probes and easily document/report the results. Automatic calculations make it a snap! All measurement data is displayed as instrument readings, tables, or graphs. The measurements can be quickly saved as PDF or Excel files. The App creates custom reports which can be saved and/or shared by email. All your data can be stored and retrieved saving you hours of time consuming paperwork!

• Measures high-side or low-side refrigerant pressure (or both simultaneously with 2 probes) in AC/refrigeration systems
• No hoses required! Clean, simple, accurate.
• Low-loss refrigerant pressure testing!
• Use with 115i pipe-clamp temperature probes for automatic superheat / sub-cooling calculations
• Measurement data is transmitted to the convenient and powerful testo Smart Probes App in your smart device
• Tough, accurate, and easy-to-use.
• For all HVAC/R technicians and contractors
