OCEMS Online Continous Emission Monitoring systems Model ATS 208A Applied Model ATS 208A Micro controller NDIR based gas analyzers are suitable for measuring sample gases in both high and low concentrations. ATS-208A OCEMS are independently developed by Applied Techno Systems, based on years of experience in research and development, for domestic and overseas environmental and industrial control monitoring online analysis. Based on micro-flow infrared technology, OCEMS are able to measure the SO2, & NOx with high accuracy and reliability, fast response, wide self-developed and industrial measurement range and application fields. Widely used in environmental online monitoring, industrial process control, safety monitoring, integrate into OCEMS, etc. As they are highly durable, even when exposed to oxidizing compounds, they offer long service lives and low life-cycle costs. Measuring the exhaust gas is an excellent way to optimize fuel and air input. Applied manufactures continuous and portable analyzers for this purpose. A flue gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion.
