Rack 3U monitor using the TDL (Tunable Diode Laser) extractive technology to measure online the NH₃ pre and/or post catalyst: SCR (Selective Catalytic Reduction) or SNCR (Selective Non-Catalytic Reduction) processes. It is also available in its turnkey analysis benches for continuous engine gas measurements.

In DeNOx systems using urea injection with ammonia (NH₃) as a reducing agent, the flow rate and control of NH₃ must be continuously adjusted and controlled to prevent excess NH₃ emissions (slip), thus reducing environmental impact and cost of reagents. Therefore, to optimize this process, it is necessary to use a continuous emissions analysis system for the online monitoring of NH₃.
