• Determination of high and low pressure, automatic determination of condensation and evaporation temperature and calculation of superheating/subcooling. 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)
• Application testo 550i
• Complying with manufacturer's specifications
• Some manufacturers specify exactly what the absolute pressure must be for you to evacuate your air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
