The Testo 550 instantly displays superheat and subcooling for up to 60 refrigerants. It also measures high / low side pressures and temperatures. With its free Bluetooth linked app, the Testo 550 opens up new possibilities for efficient analysis and documentation.
The rugged housing of the Testo 550 digital manifold includes a metal frame around the display, which protects the digital manifold from impact. Now with 60 refrigerant profiles and added functionality for leak tests, the Testo 550 digital manifold is versatile enough to become the tool for every job. You can view measurement data on your smartphone or tablet, enabling you to quickly and conveniently complete and document your job. Then, be able to finalize the documentation and send the report and invoice via email, right from the job site. The app can also be used to download new refrigerants from online, directly to the manifold.
