Extractive Laser Gas Monitors


TDL Sensors offers high-sensitivity and highly selective gas monitoring systems for a wide range of applications.  Each system is constructed from our modular core components for different gases, multiple gases and measurement ranges. 

The extractive configuration uses our robust and stable modified Herriott type mulitpass cell and our embedded control electronics housed in a 19” rack enclosure. There are options for different cell coatings and heating of the cell for specialised applications.
