    Testo 550 Refrigeration Manifold Hose Kit

    The Testo 550 Manifold Hose Kit features a refrigeration manifold gauge alongside a set of useful hoses. The set is designed for refrigeration and air-conditioning engineers who require a refrigeration manifold set with all the necessary accessories.

    The Testo 550 Refrigeration Manifold Gauge can measure pressure (0 to 60bar), temperature (-50˚C to 150˚C) and vacuum (-1bar to 0bar), thus allowing the user to perform leak tests and watch superheating and subcooling in real time. The simple push-button operation allows the user to switch between parameters as required. 39 different refrigerant profiles are stored in the gauge.

    Results are shown on the large digital screen and the instrument can even wirelessly communicate readings to a smartphone via Bluetooth wireless connectivity. All the user needs to do is download the Testo Refrigeration App to their smart device.

    Three hoses are supplied in the Testo 550 Kit. This set of colour-coded (red, blue, yellow) hoses measure 1.5m in length and have a working pressure of 55bar along with a burst pressure of 275bar. Each hose has one 7/16” UNF straight connection and one 45˚ UNF angled connection. They are ideal for two-way pressure and vacuum measurement.

    In order to measure temperature, the Testo 550 Kit comes with two clamp temperature probes. They are capable of measuring pipe surface temperature from -50˚C to 150˚C and therefore allow the user to measure differential pressure between an inflow pipe and outflow pipe.

    Other accessories in the Testo 550 Kit include batteries, a calibration protocol and a hard transport case. It is a great option for those who want an all-in-one refrigerant manifold solution.
