Gauge Readings For R22
BlogGauge Readings For R22 - For a low pressure gauge, a reading of 25 pounds per square inch (psi)to 40 psi is optimum. On the other hand, a high pressure gauge should read between 225 psi and 250 psi. In the picture, the manifold valve to the blue hose is closed so the blue gauge is measuring the pressure inside the running system. The vapor pressure is 118 psig and. Reading r22 hvac gauge r22 refrigerant operates at a relatively low pressure compared to modern alternatives. Hook hvac gauges to the units high and low refrigerant lines that can read the refrigerant type. Enter the temperature in either f or c degrees and the returned result is the alternate temperature and determined pressure in barg and psig. Barg is the gauge read pressure.
