Just switch on, measure, and read. The large figures allow the values to be read off the display quickly and easily. Two temperature-compensated pressure sensors measure high and low pressure quickly and precisely, and automatically calculate the temperatures. A glance at the instrument display is enough, and you see the measurement result.

Two temperature inputs guarantee you the simultaneous calculation and display of superheating and subcooling. The temperature can additionally also be displayed. By simply pressing a button, you can switch between the measurement tasks at your will.

The pressure ranges of the Testo 550 has been increased to 60 bar, the battery life extended to 250 hours, and there are 60 common refrigerants stored in the instrument. A new metal frame around the display has also been installed, making the instruments more robust than ever.


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.
2-way valve block with three connections, three hose parkers and sight glass.
60 current refrigerants are included in the manifold (update possible via app).
250 hours‘ battery life.
