testo 550s Smart Kit

The kit for wireless measurements in the field of commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps: You will get the testo 550s smart digital manifold with Bluetooth and 2-way valve block, two testo 115i wireless clamp thermometers (Bluetooth, NTC) and a robust transport case. Additional Bluetooth probes, e.g. for wireless, hose-free vacuum measurements with the testo 552i, are available separately.

All results at a glance thanks to the large graphic display
Exceptionally compact and reliable thanks to the easy-to-handle, robust housing with IP 54 protection class
Easy, wireless, flexible measurements and documentation: Temperature and vacuum measurements via automatic Bluetooth® connection, testo Smart App for documentation and lots more

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)
