Testo 557s Smart Vacuum Kits with 4-Way Valve Block

The Testo 557s Manifold with Bluetooth and 4-way valve block has been designed for commissioning, servicing and maintenance of refrigeration systems and heat pumps.

The Testo 557s digital manifold with 4-way valve block enables you to carry out your measurements on refrigeration and air conditioning systems and heat pumps fast and efficiently. Stored programs guide you through the measurement and enable the automatic test sequences for those all important parameters such: superheat, pressure drop test and evacuation. Evaluate your results at a glance in graphical format on the Testo 557s large, clear display.

Thanks to the testo 552i Bluetooth Vacuum Probe included in the kit, the testo 557, as the the first manifold ever, makes wireless vacuum measurement possible!

  • Exceptionally compact and reliable thanks to the easy-to-handle, robust housing with IP 54 protection class
  • Simple, wireless measurement of vacuum and temperature via automatic Bluetooth connection
  • All results at a glance on a large graphical display
  • Even greater flexibility for your measurements and documentation with the testo Smart App
  • Even easier to get results, thanks to guided measurement menus for target superheat, vacuum and pressure loss
  • Convenient refrigerant management in the App with favourites and automatic updates
  • Can be used for applications with A2L refrigerant, taking into account the relevant legislation, norms and guidelines for refrigeration systems
