Automated Vocs Gas Analyzer CEMS Monitoring System For Non Methane Total Hydrocarbon
>>Overview
Used for real-time online monitoring of volatile organic compounds (VOCs) emissions from industries such as petrochemical, painting, injection molding, coatings, textile, pharmaceuticals, electronics, and automobile manufacturing.
The system uses a high-temperature-resistant diaphragm pump to extract exhaust gas, which is then pre-treated for dust removal before being sent to the gas chromatograph for analysis. By combining catalytic oxidation and FID principles, it can quickly and effectively obtain monitoring data.
>>Feature
1) Uses catalytic method with minimal background interference, fast analysis cycle, and quick real-time data response.
2) High detection sensitivity and low resolution.
3) High catalytic efficiency and long lifespan.
4) Fully automated system design with fault alarms for easy maintenance and repair.
