The Testo 550i is compatible with the following Testo Smart Probes:
Refrigeration systems, air conditioning systems, heat pumps
Determination of high and low pressure, automatic determination of condensation and evaporation temperature and calculation of superheating/sub cooling. All the results can be read simultaneously on one display (in conjunction with the appropriate Testo Smart Probes).
Tightness test: Recording and analysis of the pressure curve.
Automatic calculation of the target superheat (in conjunction with the testo Smart App and the appropriate Testo Smart Probes, e.g. testo 115i and testo 605i).
Evacuation: Graphic progression display of the measurement with indication of the start and differential value (in conjunction with the appropriate Testo Smart Probe, e.g. testo 552i vacuum probe).
