Using the Checkmate device, a drop of oil can be milked off the suction side of a system. The Oil will be seen wetting through the Detector Tubes’ Transfer Agent. As the Oil passes through the Transfer Agent a dye fraction will release and stain the Indicator Segment. The color captured by in the Indicator is compared against a color chart.
Simply insert a Detector Tube into the Checkmate body and connect inline to a cylinder or on the low side of the system. Detector Tube results take less than one minute.
The Checkmate method is the industry’s only valid field test for measuring acid and moisture levels in both the compressor oil and any refrigerant gas. The Detector Tubes have been tested for accuracy by Intertek Testing Services, an ARI approved laboratory.
