OM - 1100 is an 5 gas analyzer based on a single beam NDIR
(Non-dispersive Infrared) measurement technology. It uses an
internal proprietary optical bench using a NDIR technique for gas
analysis. The infrared light source filters and detectors are
thermally stabilized under micro-processor control technology to
measure accurate values of Carbon monoxide (CO), Hydrocarbons
(HC), Carbon dioxide (CO2), Oxygen (O2) and Nitrogen Oxides (Nox)
coming from exhaust emission of vehicles.
