What is the normal pressure for a Freon gauge?

[Sylvia]

For car air conditioning, the low pressure when adding Freon is 1.5 to 2.5 kg, and the high pressure is 13.5 to 15.5 kg. Pressure gauge kilogram readings: When checking the Freon pressure gauge for car air conditioning, you can observe whether the kilogram reading is high. The outer red circle ranging from -30 to 350 LB/IN2 represents imperial pressure units, while the inner circle ranging from -0.1 to 2.5MPa shows the commonly used pressure units. Pointer position: When not pressurized, the gauge's pointer rests at the 0 mark. During normal air conditioning operation, the pointer should indicate around 0.5MPa. 0.1MPa is approximately equal to 1.0197 kg/cm2 or 0.987 atm, meaning the normal operating pressure for air conditioning is about 5.0985 kg/cm2.
