How to use the refrigerant pressure gauge?
Check suitability: Make sure the refrigerant pressure gauge is suitable for the type of refrigerant used (such as R22, R410A, etc.).
Connection: Connect the pressure gauge to the low-pressure and high-pressure sides of the refrigeration system.
Reading: Read the pressure value according to the working status of the refrigeration system (on or off). According to the pressure value, the state of the refrigerant (such as charging amount, operating efficiency, etc.) can be judged.
Operation precautions: Avoid refrigerant leakage during use, ensure tight connections, and wear appropriate protective equipment.
