AC Gauges Digital HVAC Manifold Gauge Set for 93 Refrigerants AC Pressure Gauge Set R134A R22 R12 R410A R1234YF Home Car Automotive Refrigerant Recharge Kit Refrigeration Hoses with Low Loss Fittings

  • ...32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Digital refrigerant gauges can also calculate the supercooling and superheating degree, which is convenient to read the data directly during the operation. In addition, the ac manifold gauge set tests the percentage of vacuum measurement.
  • pressure leak measurement, and leak time speed record..
  • 【Visualization Window & Refrigerant Charging & Vacuum Operation】Through the window of HVAC digital gauges, the charging state of the refrigerant can be directly observed, which is more convenient to operate. The HVAC digital manifold gauge set can realize vacuum operation by connecting the refrigeration equipment and vacuum pump. Note: When the gauge is turned on, there may be 10 digits in the high and low-pressure display area. At this time, press the zero button long until it returns to zero..
  • 【Pressure Leak Test】The manifold gauge calculates the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking. The digital HVAC manifold gauge set is specially used for the installation, testing and maintenance of refrigeration equipment such as air conditioners, refrigerators, and cold storage..
