testo 557s Digital Refrigeration Manifold Smart Vacuum Kit

Start your wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. Thanks to the Bluetooth vacuum probe supplied, you can even measure vacuum without any cables or hoses. You will get the testo 557s smart digital manifold with Bluetooth and 4-way valve block, one testo 552i wireless vacuum probe (Bluetooth), two testo 115i wireless clamp thermometers (Bluetooth, NTC) and a robust transport case. For other wireless measurements, other optionally available testo Smart Probes are also ideal.

- Completely wireless measurements and all results at a glance: thanks to Bluetooth probes and 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)
