Who Is TRI Air Testing?

TRI Air Testing, an AIHA-LAP, LLC accredited laboratory, provides worldwide compressed air and pure gas testing as well as other compressed pure gas testing for fire service, SCUBA, OSHA, medical, manufacturing, pharmaceutical, biotech, food/beverage, industrial companies and the Government/Military.

TRI Air Testing proudly pioneered the science of compressed air and pure gas testing.  TRI’s patented air/gas sampling equipment was designed in 1975 for the U.S. Navy Divers. Since then, TRI Air Testing continues to sponsor the U.S. Navy and Coast Guard D.C.A.T. program as well as other branches of the United States military. Our foundation is compressed air testing, however we are one of the industry leaders in pure and blended gas testing as well. TRI Air Testing has the ability to test up to ultra-pure standards of the “5 9’s” (99.999%) for all gaseous components in the atmosphere, inert gases, propellant and fuel gases, and all various gas blends. Over the years, TRI Air Testing has gained vast experience servicing a wide variety of industries. We provide a no cost consultation to help assess testing needs and create customized solutions to international standards for an individualized compressed air and pure gas testing program.
