Product Description

High Temperature UV Flue Gas Monitoring System



High Temperature UV Flue Gas Monitoring System Gasboard-9070 is based on advanced UV-DOAS gas analysis technology, which can simultaneously measure the concentration of SO2, NO, NH3 and other gases. It adopts multiple reflection chamber to reach a lower limit of detection. The system adopts high temperature tracing on whole sampling circuit to ensure high measurement accuracy, that can be widely used to monitor the flue gas from industrial stacks or stationary pollution source before and after desulfurization and denitrification, and accurately reflect the conditions of ammonia escaping.




• Adopt UV-DOAS technology to measure SO2, NO, NH3 gas concentration simultaneously with high accuracy.
• Using multiple reflection gas chamber to provide ultra-low range measurement and low detection limit.
• High temperature tracing on entire gas flow path, adopting low-adsorption materials and processing techniques to effectively avoid the loss of SO2 and NH3.
• Extractive measurement method, not affected by dust, temperature, and pressure fluctuations in the flue.
• Built-in automatic correction algorithm to eliminate interference from other gas components.
• Automatic calibration design, easy for operation and maintenance.
• Widely applicable on different applications, not restricted by on-site installation conditions.
