    Testo 557 Digital Refrigeration Manifold Set

    The Testo 557 Digital Refrigeration Manifold Set allows HVAC/R service engineers to perform multiple tests on refrigeration and A/C systems and heat pumps. These include a leak test, refrigerant flow, charging and system evacuation using the integrated vacuum measurement aids.

    Now featuring bluetooth compatibility, the Testo 557 Digital Refrigeration Manifold can be used in with the new Testo Refrigeration App. Providing a remote view of your measured values on a Smartphone / Tablet, this app allows you to track changes using the graphical trending function, update the refrigerants in the instrument, create .pdf or .csv (Excel) reports and more, ensuring you get the most from your new digital manifold.

    Testo 557 Set Features:

    • Calculate superheating and subcooling simultaneously
    • Integrated vacuum measurement supports the evacuation of systems
    • Temperature-compensated tightness test
    • Automatic ambient pressure measuring
    • 40 refrigerants are stored in the instrument
    • 4-way valve block for fast and efficient work
    • Bluetooth Compatibility

    A built in vacuum measurement allows users to know when they have successfully evacuated a refrigeration system, while the two temperature inputs mean that superheat and subcooling can be simultaneously calculated and displayed in real-time along with differential temperatures.

    The Testo 557 is a four valve manifold that allows for the connection of a vacuum pump and refrigerant tank at the same time, which minimises the chances of exposing the system to the atmosphere during commissioning. In addition, the automatic heat pump mode means the hoses no longer need to be switched over during testing.

    Ideal for servicing, maintaining and commissioning air conditioning and refrigeration systems, the Testo 557 Refrigeration System Analyser is supplied complete with 2 pliers probes, a calibration protocol and hard transport case.
