Due to stringent regulations, some facilities are required to install aftermarket pollution control systems to reduce criteria pollutant concentrations such as NOx and SO2. In order to control the performance of the pollution control system, monitoring systems are located before and after the control device(s). C.E.M. Solutions provides process monitoring systems designed to operate in a variety of flue gas environments, including high temperature, particulate laden gas streams. These process monitoring systems are constructed for reliability, repeatability, and fast response times. The process monitoring systems offer the same reliability and equipment as our CEM systems.
