The LaserCompact is an adaptable analyzer optimized for measuring gases in-situ across short pathlengths. Capable of monitoring a wide range of gases including O2, HCl, HF, NH3, CO, CO2, H2O and H2S. This analyzer uses leading-edge Tunable Diode Laser (TDL) sensing technology, providing a fast speed of response, zero drift potential and minimized background gas interference. This makes it ideal for diverse applications including chemical production, contaminant and moisture monitoring in petrochemical processing, non-contact analysis of corrosive, dusty, tarry or sooty gases across pipes and engine test stands. 

Optimized for use in hot dirty or dangerous environments, the LaserCompact features a robust design and easy installation on measurement cells or DN50/ANSI flanges, allowing safe operation in situations where the process stream itself is flammable and has been classified as a Hazardous Area. This device also requires minimal ongoing
maintenance, helping to reduce operational costs
considerably over product life.
