ONLINE CONTINUOUS EMISSION MONITORING SYSTEM

ONLINE CONTINUOUS EMISSION MONITORING SYSTEM
stack-gas analysis systems have a smaller footprint, and use cross-flow modulated non-dispersive infrared (NDIR) detection with a magnet-pneumatic detection method that is inherently drift-free. This series are superior continuous analysis systems that are perfect in the difficult field of exhaust gas measurement, where measurement errors cannot be tolerated. The series features a new intuitive touch panel that makes every operation available with the touch of a single button. This series systems are also designed for faster, more efficient maintenance. They are ideal for a variety of uses, including monitoring steam boiler, refuse incinerator, and electric power generation plant emissions to assure pollution standards are being met.
FEATURES
- its innovative optical technology enables ENDA-5000 series measure up to five components which can be arranged any combination.
- The interference correcting sensor uses a unique interference filter to compensate for the influence of interference by other gases.
- In addition to the alert functions available in the past, the ENDA-5000 series feature extra alert functions. A continuous checking process can prevent the unit from stopping due to a failure, reducing the risk of failed measurements and assuring consistent operation.
- Corrections of SO2 measurements using wet base methods of the past took a great deal of time (about 15 minutes), but with the ENDA-5000 series’ dry base method, correction takes only three minutes.
- Instantaneous output (NOx, SO2, CO, CO2, O2) O2 calculated output values (NO2, SO2, CO) Moving average values (for one to four hours)
