testo 549i - Refrigeration pressure wireless Smart Probe

Order-Nr.  0560 1549

  • Measures high-side or low-side refrigerant pressure (or both simultaneously, with 2 probes) in AC and refrigeration systems

  • No hoses required; clean, simple, and accurate

  • Low-loss refrigerant pressure testing!

  • Use with the testo 115i pipe-clamp temperature probes for automatic superheat and subcooling calculations

The testo 549i Smart Probe is a hoseless, wireless pressure probe for measuring refrigerant charge in AC and refrigeration systems.  It is used for servicing, troubleshooting, and documenting the operation of residential or commercial AC and refrigeration systems.  When two testo 549i probes are used in conjunction with two testo 115i pipe-clamp temperature probes, it is easy to monitor superheat and subcooling in AC and refrigeration systems.

Product Description

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 feet.

The testo Smart Probes app is a powerful and easy to use tool.  It allows you to remotely read measurements from up to six (6) Smart Probes, and easily document and 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!
