The Testo 549 Digital Refrigeration Manifold Kit (Replaces the Testo 550-1) enables users to perform a range of measurements including pressure, vacuum and temperature using just this one instrument, saving time and improving accuracy.

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 on the Testo 549 By simply pressing a button, you can switch between the measurement tasks at your will.


Calculation of superheating/subcooling in real time with up to two external temperature probes.
2-way valve block with three connections, three hose parkers and sight glass.
60 common refrigerants stored in the instrument.
Two temperature-compensated pressure sensors.
Display illumination for better legibility in dark surroundings.
250 hours‘ battery life.
