testo 550i Digital Refrigeration Manifold Smart Kit

The kit for app-controlled, wireless measurements and digital documentation on your smartphone. You will get the testo 550i app-controlled digital manifold with Bluetooth, 2-way valve block and sturdy hook, two testo 115i wireless clamp thermometers (Bluetooth, NTC) and a robust transport case. For other wireless measurements, the optional Testo Smart Probes for temperature, humidity and vacuum are the perfect addition. You’ll be ideally equipped to carry out your measuring tasks on refrigeration and air conditioning systems and also heat pumps.

- 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

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)
