testo 550i Smart Kit – App-controlled digital manifold with wireless clamp temperature probes (NTC)

  • All activities, from measurement through to documentation, using the App on your Smartphone
  • The smallest digital manifold on the market
  • Maximum reliability and excellent flexibility: extremely robust housing with protection class IP54, optionally expandable with the wireless testo Smart Probes for temperature, humidity and vacuum
  • In the kit: App-controlled testo 550i digital manifold with Bluetooth® and 2-way valve block, 2 x testo 115i wireless clamp temperature probes (Bluetooth, NTC), case

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 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)
