Who Tests the Air and Pure Gas Testers?

TRI Air Testing, Inc. Vice President, J. Michael Carlson decided several years ago to answer the question, “Who Tests the Air Testers?” The American Industrial Hygiene Association (AIHA) proficiency testing sub-committee with input from three other founding laboratories developed and is currently administering the Compressed Air Proficiency Testing Program (CAPT).

Over 30 air and pure gas testing laboratories participate in the round-robin compressed air and pure gas proficiency testing group. The unknown air sample is prepared by an ISO-9000 registered gas supplier. By participating in quarterly Compressed Air Proficiency Testing Program (CAPT) we are able to compare our test results of an unknown sample of air and pure gas to the test results of other participating laboratories throughout the World.
