AAI’s TDL analyzer measures the concentrations of gases. AAI’s Process analyzers are all optically based, where the absorbance of light by matter is correlated to stream composition. The TDL-506 includes a tunable diode laser as a light source and a InGaAs detector, measuring light lost following the interaction with the sample gas molecules.

AAI 's analyzer for In-situ monitoring include the following features:

• Operation in hazardous areas High accuracy
• Low detection limits
• Long-term stability
• Low maintenance requirements
• Wide Concentration measuring range Fast response
• Low cost of ownership
