AIM designs, develops and manufactures proprietary World Class gas analyzers and complete systems for environmental monitoring [ambient air, vehicle exhaust and stack gas emissions], with installations in 35 countries. AIM's patented analyzers include EPA compliant, fast response, in-situ, extractive, fiber-optic coupled and remote sensors, using NDIR, NDUV, dispersive UV and/or dispersive IR spectroscopy, measuring from 1 to 10 or more gases per analyzer. In addition we assemble systems incorporating not only the AIM sensors, but also O2, FID, chemiluminescence, fluorescent, FTIR or other analyzers. Our most popular products are both exclusively our designs, our in-situ [non-sampling] stack gas monitors, and our fast response across-the road remote vehicle exhaust analyzers.
