R404A PT Chart: Pressure Temperature Chart For -49°F To +150°F
Just check the R404A PT chart below and you will see that the pressure of 404A liquid at 85°F is 189.5 psig and the pressure of 404A vapor is 187.5 psig at the same temperature. We use gauge meter to measure the pressure of R404A refrigerant at different temperatures.
