Advantages
  • All activities, from measurement through to documentation, using the testo Smart App on your Smartphone;
  • The smallest digital manifold on the market;
  • Maximum reliability thanks to the extremely robust housing with IP54 protection class;
  • Optionally expandable with testo Smart Probes for temperature, humidity and vacuum.
 
Industries
  • 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);
  • 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);
  • 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);
  • Tightness test: recording and analysis of the pressure curve.
