1Temperature Pressure Measurement: The gauge can measure dual pressure (gauge pressure) at the same time, as well as dual temperature measurement, (requires test clip, not included), with automatic multi unit pressure conversion, automatic temperature conversion and . 2Multi Kinds of Refrigerants: Built in 92 kinds of refrigerant pressure, evaporation temperature database, and can also calculate subcooling and superheat degree, which is convenient to directly read the operation process data. 3Multifunction: Refrigeration digital manifold meter also tests percentage of vacuum measurement, pressure leak measurement, leak time speed recording. Digital manifold gauge is multifunctional, accurate and easy to operate. 4High Accuracy: The instrument has a built in 32 bit digital processing unit and a high accuracy data acquisition unit, with high stability, and adopts high strength engineering plastics and flexible nonslip silicone, which is sturdy and comfortable to hold. 5Lcd Display and 1/4in Interface: Designed with large size Lcd display, Lcd backlight support, the data display is clear and easy to read, light and easy to operate. Long life valve switch, 1/4in standard interface design. 6Practical Tool: The intelligent electronic vacuum pressure temperature tester is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners and cold storages.
