Checkmate Kit

Part Number: RT700K

The Checkmate method is the industry’s only valid field test for measuring Acid and Moisture levels in both the compressor oil and in any refrigerant gas. Since it’s introduction in 1995, Checkmate is now used by refrigerant packagers, reclaiming companies and thousands of service contractors all over the world. The detector tubes have been tested for accuracy by ETL, Intertek Testing Services, an ARI approved laboratory.

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.

  • Heavy wall pyrex glass is used on each tube and packed under dry nitrogen, and the high quality brass body is coupled with HG 316 stainless steel needles.

  • Refrigerant oils are the opposite of engine oil in nature. They are hygroscopic (absorb moisture), and engine or petroleum oils are hydroscopic (repel moisture).

  • ISO4406 states that PAG and POE oils must not exceed a moisture content of 350ppm.
