Features: Multifunctional tester, can test vacuum pressure, pressure leakage, switch between refrigerant gauge and vacuum gauge, refrigerant operating condition pressure, condensation and evaporation temperature measurement. The pressure-holding leak test function of the instrument is mainly used to test the leakage of the refrigeration system. The test pipeline is pressurized to a certain value (or vacuum state) and then stopped, and the pressure changes within a period of time. Built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate the subcooling superheat, to facilitate direct reading of operating process data. Backlit large screen, clear data, no need to worry about the dark environment. Long-life valves switch, 1/4-inch standard interface design to ensure that the instrument’s durability and versatility. Intelligent electronic refrigerant group instrument is an auxiliary instrument for the installation, inspection and maintenance of refrigeration equipment such as air-conditioning, refrigerator, cold storage.
