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.

Automatic superheating/subcooling calculation: no more need for manual calculations, which are prone to error With a practical app: (remote) display, graphical progress display, documentation of readings Temperature-compensated leakage test 60 current refrigerants are included in the manifold (update possible via app)
