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)

This item comes either without hoses or as a kit with a set of 3 hoses.
