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!

Features:

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
