RA18759 Robinair Air Purge Gauge And Thermometer gives the operator a visual cue as to the air content of a cylinder during recycling mode. Operates on a pressure temperature equivalence similar to a pressure temurature chart. The temp scale reads from the red needle and the pressure scale reads from the green needle. Al that is needed is to compare to a P/T chart for the given refrigerant and compare pressures to determine if air is present. (requires the well or similar device to obtain accurate readings of refrigerant in flow).
