    Testo 550 Digital Refrigeration Manifold Set

    The Testo 550 Digital Refrigeration Manifold Set 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 Set is supplied complete with two pliers probes for temperature measurements and a rugged transport case with space for your 550 digital manifold and accessories.

    Upgraded to feature bluetooth compatibility, the Testo 550 Digital Refrigeration Manifold can now be used in conjunction with the new Testo Refrigeration App. Offering a remote view of your measured values on a Smartphone / Tablet, the 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 digital manifold.

    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 Set 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 Digital Refrigeration Manifold Set, multiple tests can be performed and calculated in a short space of time. Service engineers can perform a leak test 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 the performance and efficiency of the system.
