Digital manifold for all-rounders

The practical kit makes it even easier to work on air conditioning and refrigeration systems: the testo 550 digital manifold, including set of 3 filling tubes, enables you to get down to work straight away! The instrument can be used for 60 refrigerants, calculates superheating/subcooling automatically and can be connected to your smartphone/tablet via the testo refrigeration App. Thanks to the App, the display and documentation of the measurement results are particularly convenient.

• Extensive accessories included: set of 3 filling tubes, 2 x clamp temperature probes and transport case

• Automatic superheating/subcooling calculation for 60 refrigerants: no more need for error-prone manual calculations

• With a practical App: (remote) display, graphical progression display, documentation of readings and refrigerant updates

• Temperature-compensated leakage test

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)

Practical kit for work on air conditioning and refrigeration systems, as well as on heat pumps: the testo 557 digital manifold, including set of 4 filling tubes, enables you to get down to work straight away! The testo 557 digital manifold fulfils numerous functions in just one instrument: including superheating/subcooling calculation, vacuum measurement and temperature-compensated leakage test. You can also use a practical App to monitor the manifold via your smartphone/tablet and to store the measurement results or send them by e-mail.

• Extensive accessories included: set of 4 filling tubes, 2 x clamp temperature probes, precise external Pirani gauge for vacuum measurement and transport case
   

• Calculation of superheating and subcooling in real time for 60 refrigerants: no error-prone manual calculation

• Connection to smartphone/tablet App: remote monitoring, clever measurement documentation and refrigerant updates

• Temperature-compensated leakage test, automatic ambient pressure measurement

The testo 557 digital manifold fulfils numerous functions, which are required for working on refrigeration systems and heat pumps, in just one instrument: for example superheating/subcooling calculation, vacuum measurement, temperature-compensated leakage test. You can also use a practical app to monitor the manifold via your smartphone/tablet and store the measurement results or send them by e-mail.

• Calculation of superheating and subcooling in real time: no manual calculation, which is prone to error

• Connect to smartphone/tablet app: remote monitoring and smart measurement documentation

• Precise external Pirani gauge for vacuum measurement, temperature-compensated leakage test, automatic ambient pressure measurement

• The 60 most common refrigerants are stored in the instrument, subsequent updates possible (via app)
