Product Overview
This low-range online flue gas analyzer is based on proprietary non-dispersive infrared (NDIR) gas analysis technology. Its half-cell gas pathway design ensures high precision and minimal drift, significantly reducing interference from environmental factors like temperature and voltage fluctuations. Designed specifically for the online monitoring of low-concentration flue gases, it is ideal for environmental monitoring and precise industrial emissions control.
Key Features
- Ultra-Low Range: Measures down to 200 ppm, meeting national standards for low-concentration emissions in environmental sectors. With a resolution of 1 ppm, it supports certification for low-concentration gas emissions.
- High Measurement Accuracy: The innovative half-cell pathway design, combined with NDIR technology, minimizes drift and external interference, ensuring no cross-interference between multiple gas components.
- High Automation & Low Maintenance: Equipped with a built-in pre-processing system, it supports real-time online monitoring without requiring manual oversight, reducing labor costs.
- Simple Data Management: Multiple interface options allow for easy integration with centralized control systems, enabling centralized data transmission and management.
- Self-Diagnosis & Auto-Zeroing: Features sensor self-diagnosis and auto-zeroing with ambient air, ensuring stable measurements over extended use.
Applications
- Environmental Monitoring: Monitors low-concentration flue gases to ensure industrial emissions comply with environmental standards.
- Industrial Sector: Suitable for low-concentration gas monitoring in facilities like power plants, chemical factories, and cement plants.
- Research and Testing: Ideal for low-concentration gas analysis in academic and research institutions.
- Emissions Control: Enables precise gas composition control for managing corporate pollution emissions effectively.
