Product Overview
The Ultraviolet Flue Gas Analyzer is designed by Sifang Instruments, based on ultraviolet differential absorption spectroscopy (UV-DOAS) gas analysis technology, specifically for real-time online monitoring of flue gas components. The instrument features a unique long optical path multi-pass gas chamber structure, offering high sensitivity, strong absorption signal capabilities, and excellent stability, making it particularly suitable for ultra-low emissions monitoring. It can simultaneously measure the concentrations of gases such as SO₂, NO, and NO₂, meeting the demands of industrial environmental protection emissions monitoring.
Key Features
- High Sensitivity & Accuracy: Uses an imported deuterium lamp as the light source, ensuring stable performance with a linear error as low as ≤±1% F.S.
- Strong Environmental Adaptability: Stable temperature control reduces the impact of environmental temperature fluctuations on measurements.
- Low Cross-Interference: Optimized absorption peaks and interference compensation algorithms significantly reduce cross-interference between gases.
- User-Friendly Operation: Equipped with a 7-inch color touchscreen, providing an intuitive interface for easy operation.
- Automatic Calibration: Includes a pump and valve control function for automatic calibration and gas pathway control, ensuring measurement accuracy.
- Multiple Output Interfaces: Supports RS232, RS485, and 4-20mA outputs, complying with environmental data collection standards.
Applications
- Environmental Monitoring: Widely used in industries such as power generation, chemicals, and metallurgy for flue gas emissions monitoring, helping companies meet environmental regulations.
- Ultra-Low Emission Detection: Ideal for monitoring emission sources with ultra-low emission requirements, such as coal-fired power plants and steel mills.
- Industrial Emissions Control: Real-time monitoring of industrial emissions to ensure compliance with environmental regulations and reduce pollution.
- Research and Laboratory Use: Serves as a research tool for flue gas analysis and new material development in laboratory applications.
