The testo 550 digital manifold can now make working on refrigeration systems and heat pumps even easier: the instrument can be used for 60 refrigerants, calculates superheating/subcooling automatically and can now also be connected to a practical smartphone/tablet app. The app makes the operation and the documentation of measurement results significantly more convenient.
(1) Automatic superheating/subcooling calculation: no more need for manual calculations, which are prone to error
(2)With a practical app: (remote) display, graphical progress display, documentation of readings
(3)Temperature-compensated leakage test
(4)60 current refrigerants are included in the manifold (update possible via app)
Features
Right app for the instrument: connect the manifold to your smartphone/tablet!
Install the free app for the testo 550 digital manifold on your smartphone/tablet and take advantage of a host of practical features:
The app is available for both Android and iOS. Once the app is installed, a connection between the manifold and your smartphone/tablet can be established via Bluetooth.
