ENDA-C2000 Stack Gas Analyzer System
Overview
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.
Features
- The units are equipped with a new drift-free chemiluminescent analysis (CLA) device.
- The units are capable of a minimum range of 0ppm-10ppm for NH3 and NOx.
- The units are equipped with a revolutionary magnetopneumatic method oxygen analysis device that works using oxygen's ordinary magnetism.
- Front-panel operation offers enhanced ease of use.
- Equipped with numerous functions, such as computer monitoring of analysis conditions, control, data processing, and memory, the units are simple to use and require minimal maintenance.
- The units are fully equipped with self-diagnostic functions.
- The units can be configured to meet the needs of a wide range of installation sites.
