Stack Emission Monitoring System/Analyzer

Stack Emission Monitoring System/Analyzer

Drexel Group is a manufacturer of Online Pollution Monitoring systems for Water Quality Monitoring, Emission, and Ambient Air Quality Monitoring like Stack Emission Monitoring System/Analyzer.

Drexel Emission Monitoring Systems is required to analyze the harmful/toxic gases discharged from Industrial stacks as per the emission parameters specified for the industry depending upon the specific industrial process.

Stack Emission Monitoring is a process to measure the emission level of industrial plants or pollutants emitted into the atmosphere by the stacks connected to industries. The pollutants emitted from the stack can be solid particulate matter and waste gases.

Continuous stack emission monitoring enables 24-hour monitoring of the emission levels of the plant. This is essential to protect the environment and also the authorities can excess the online data through servers connected to online emission monitoring systems. This monitoring of emission levels is vital for big plants like cement plants, refineries, and large-capacity chemical plants.

Stack Emission Monitoring System/Analyzer


Our DX4P is a multi-parameter system, and it works on an extractive measurement technique wherein the emission levels are measured by extracting the heated gas from the stack, and before feeding to the analyzer it is cooled to the required sampling temperature. The Stack gas parameters are measured with NDIR, NDUV, FTIR, and DOAS principles.
