Parameters: SO2, CO2 (optional: NO)
IndustriesEmission Monitoring
Overview
Gasboard-9085 is a marine CEMS compliant with MARPOL Annex VI, GB15097-2016 and GD01-2011, measuring SO2, CO2, NOx, NH3 and other exhaust gases with UV-DOAS, NDUV, NDIR, GFC and TDLAS. It integrates ultrasonic flow and temperature/pressure measurement, a heated sample path and marine-grade construction, with real-time monitoring, logging and automated reporting.
Key Features
- Advanced technology platforms including UV-DOAS, NDUV, NDIR, GFC, and TDLAS for continuous measurement of SO2, NOx, CO2, NH3, and other exhaust gases.
- Multiple sampling channels design enabling cyclic monitoring across different measurement points for comprehensive emission control.
- Automated operation through PLC system with OMRON relays, managing sampling, drainage, and fault handling for reliable performance.
- Robust construction with marine-grade components, ensuring stable operation under harsh conditions with vibration, high temperature, and high humidity.
- Multiple data interfaces supporting remote monitoring, process optimization, and automated reporting for efficient operation control.
