Applications

Refrigeration systems, air conditioning systems, heat pumps

  • Determination of high and low pressure, automatic determination of condensation and evaporation temperature and calculation of superheating/subcooling. All results can be read simultaneously on one screen
  • Tightness test: Recording and analysis of the pressure curve
  • Automatic calculation of the target superheat (in conjunction with the appropriate measuring instrument, e.g. Testo Smart Probe)
  • Measure vacuum: Graphic progression display of the measurement with indication of the start and differential value
  • 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)
