    Testo 550-1 Digital Refrigeration Manifold

    This product has now been discontinued and replaced by the Testo 549 Digital Refrigeration Manifold.

    The Testo 550-1 Digital Refrigeration Manifold enables users to perform a range of measurements including pressure, vacuum and temperature using just this one instrument, saving time and improving accuracy.

    The Testo 550 Digital Refrigerant Manifold is ideal for the service, maintenance and commissioning of air conditioning systems, heat pumps and refrigeration units, allowing users to quickly charge and service these systems.

    Testo 550-1 Kit Features

    • Calculation of superheating/subcooling in real time
    • 2-way valve block with three connections, three hose holders and sight glass
    • The 39 most common refrigerants are stored in the instrument
    • Display illumination for better legibility in dark surroundings
    • Automatic heat pump mode
    • Temperature-compensated tightness test

    The automatic heat pump mode means the hoses no longer need to be switched over, while the temperature compensated tightness test and real-time calculations of superheating and sub-cooling mean the Testo 550 refrigeration system analyser makes short work of refrigeration system and heat pump maintenance.

    Using the Testo 550-1 Digital Refrigeration Kit, multiple tests can be performed and calculated in a short space of time. Service engineers can perform a leak test, monitor refrigerant flow through the integrated sight glass and watch as superheating and subcooling are displayed in real-time. At the touch of a button you can quickly switch between different measurements, with a large backlit display that clearly displays all the test values required to assess performance, reduce refrigerant losses and increase the life span of the system.
