Testo 557 Digital Manifold Kits

The Testo 557 Digital Manifold opens up new possibilities for efficient analysis and documentation thanks to the integration of Bluetooth connectivity with the Testo Refrigeration App. You can clearly read measurement data, such as automatic calculations of superheat, sub-cool and vacuum readings, on a Smartphone or Tablet, allowing you to work more quickly and conveniently than ever before. In addition, measurement reports can be created and sent directly from the job site. The 557 features an external vacuum probe for faster and more reliable evacuations and is suitable for all refrigeration systems or heat pumps. This compact manifold has a 4-way valve block, large backlit display and sight glass.
