ENDA-5000 Stack Gas Analysis System
Overview
MCERTS Certified Continuous Emission Monitoring System (CEMS) with high-precision and simultaneous measurement of NOx, SO2, CO, CO2 and O2
Over 100,000 systems installed and 30 years of quality and experience. That is the base on which HORIBA's ENDA-5000 series of Continuous Emission Monitoring System for stack-gas analysis is built. These 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. The ENDA-5000 series are superior Continuous Emission Monitoring systems (CEMs), fully certified to MCERTS standards, they are perfect for the difficult field of exhaust gas analysis, where measurement errors cannot be tolerated. The series features an intuitive touch panel that makes every operation available with the touch of a button. The ENDA-5000 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
- Continuous simultaneous measurement of up to five components with one system
The ENDA-5000 series can measure up to five components, thanks to HORIBA's innovative optical technology. Measurements of up to five components can be made in any combination. - MCERTs Certifed
The ENDA-5000 Continuous Emission Monitoring System is certified to the Environment Agency’s MCERTs standard. - Correction for interference
The interference correcting sensor uses a unique filter to compensate for the influence of interference by other gases. - Better alerts and extra alerts
In addition to the alert functions available in the past, the ENDA-5000 series systems 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. - Dramatically reduced correction time for SO2
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 system's dry base method, correction takes only three minutes.
