On the low-side R22 pressure at 85 degrees displays 60 psi, whereas on the high-side R22 pressure at 85 degrees shows 250 psi. For servicing of the compressors, the right way is to follow the service manual. The term gauge signifies that the pressure has been read from a gauge that actually measures the difference between the pressure of the fluid or gas and the pressure of the atmosphere. Psig is equal to psis at sea level (14.7 psi). Psig is equal to psia - 14.7 at sea level. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi.Temp (°F) Pressure Temp (°C) Temp (°F) Pressure Temp (°C) Temp (°F) Temp (°C) Pressure Temp (°F) Pressure Temp (°C)
