Laser Gas Detection Module NH₃ (TDLS)
Rack 3U monitor using the TDL extractive technology to measure online the NH3 pre and/or post catalyst: SCR (Selective Catalytic Reduction) or SNCR (Selective Non-Catalytic Reduction)
ENVEA offers this rackable and small footprint NH3 measurement system (3U rack) integrated in its turnkey analysis benches for continuous engine gas measurements.
Its measuring principle is based on gas detection by tunable diode laser spectrometry (TDLS) which offers many advantages and an exceptional value for the customer.
