testo 550s Digital Refrigeration Manifold Basic Kit

With this kit, you’ll be ready to start your measurements in the commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps straight away: You will get the testo 550s smart digital manifold with Bluetooth and 2-way valve block, two fixed cable clamp temperature probes (NTC) and a robust transport case. Additional Bluetooth probes, e.g. for wireless measurements of temperature and vacuum, 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)
