Low-Range Online Flue Gas Analyzer

Product Overview

The Low-Range Online Flue Gas Analyzer is a high-precision instrument designed for continuous monitoring of low-concentration flue gas emissions. Based on non-dispersive infrared (NDIR) technology, the analyzer adopts a split-flow gas chamber design to effectively minimize the impact of environmental factors such as temperature fluctuations and voltage variations. This ensures high accuracy and low drift performance.

The system is ideal for real-time monitoring and precise control of low-level emissions, and is widely used in environmental monitoring and industrial emission management.

Working Principle

The analyzer operates on the NDIR absorption principle, where different gas components selectively absorb infrared light at specific wavelengths to determine their concentrations.

The split-flow gas chamber design compares measurement and reference signals to suppress external interference, reduce drift, and improve stability. An integrated pretreatment system filters and stabilizes the sample gas before it enters the analysis unit, ensuring consistent measurement conditions.

In addition, automatic zero calibration and self-diagnostic functions continuously correct measurement deviations, enabling long-term stable operation.

Key Features

• Ultra-Low Range Measurement: Measurement range as low as 200 ppm with a resolution of 1 ppm, ideal for low-concentration emission monitoring.
• High Accuracy & Low Drift: NDIR technology combined with split-flow gas chamber design ensures precise measurement with minimal drift and no cross-interference.
• Continuous Online Monitoring: Built-in pretreatment system supports unattended operation, reducing maintenance and operational costs.
• Flexible Communication: Multiple communication interfaces allow integration with centralized control systems for data management and remote transmission.
• Reliable Operation: Equipped with self-diagnostics and automatic zero calibration to ensure long-term stability and reliability.
