Car Refrigerant Manifold Gauge Set Air Conditioning Digital Vacuum Pressure Tester Meter DY517 Temperature Test Tool Kit The intelligent electronic refrigerant group instrument is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners and cold storage. The instrument has double pressure test, dual temperature test (need test clip,not include), digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. The instrument uses high-strength engineering plastics and flexible non-slip silicone design, the whole machine is solid and comfortable to hold. Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Large-size liquid crystal, LCD backlight support, data clear and easy to read, convenient light operation. Long-life valve switch, 1/4-inch standard interface design to ensure that the instrument's durability and versatility.The instrument can measure double pressure (gauge pressure) at the same time, as well as dual temperature measurement (need test clip,not include), with automatic multi-unit pressure conversion, automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs. Built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate the subcooling superheat, to facilitate direct reading of operating process data. Also it tests percentage of vacuum measurement; pressure leak measurement, leak time speed record. It is deserved to have this multi-functional, accurate and simply operated digital manifold let you do the job right.1) The pressure measured by the digtal manifold pressure tester is gauge pressure.2) Pressure testing ranges from -101Kpa to 6Mpa (-0.1bar to 60bar).3) The limit pressure is 10 Mpa (100 bar).4) The maximum operating pressure of standard hose is 600 PSI ( approximate 4.13 Mpa, 41.3 bar ). The limit pre
