The ENDA–C2000 Series is a lineup of units for the continuous monitoring of residual NH3 contained in emissions from ammonia dry method denitrification equipment. Measurement is highly accurate thanks to the use of a new drift–free chemiluminescent analysis (CLA) device. Used in semiconductor fabrication plants, the units are designed to provide a long life. The units are simple to use thanks to such features as an integrated analysis and operating instruments, front–panel operation, and self–diagnosis. The units are well suited for denitration catalyst inspection, controlling NH3 injection volumes, the prevention of ammonium sulfate crystal formation, facilities inspection, and process control.
Applications include: Stack emmision monitor, SCR control, Desulfulization control, Green house gas monitor, Boiler emission, Gas separation, Coal fired gas, Natural fired gas etc...
