ROCKROK Automotive Air Conditioning Vacuum Pressure Gauge for Refrigerants Measurement

High stability chip, built-in 32-bit digital processing unit and high-accurate data acquisition unit, for more stable and accurate pressure data measurement. Double pressure testing, real-time vacuum degree and pressure values, provide reliable basis for judging the operating condition of refrigeration systems. Built in with 92 types of refrigerants NIST, powerful computing power, it can switch between common refrigerants at will, suitable for various maintenance situations; Intelligent diagnostic system malfunction. Recordable leakage time and speed, easy to operate, and direct reading of process data. Evaporation temperature/condensation temperature display. The greater the degree of subcooling, The better the refrigeration capacity of the refrigeration systems. The greater the degree of super heat, the smaller the opening of the expansion valves (less refrigerants charge) can be determinedly.
