Apex Instruments was established in 1988 as an American-owned company with a worldwide impact. For more than 25 years, Apex Instruments has manufactured equipment for sampling emissions from industrial chimneys and smokestacks using U.S. EPA guidelines. Our equipment is designed by a staff of experienced stack testers who understand your compliance testing needs.
