Continuous Emissions Mercury Monitor (915J)
Real-Time Speciating Hg Process Monitor
The 915J Continuous Emissions Mercury Monitor is an online mercury process monitor designed for use in challenging conditions including coal-burning utilities, cement kilns, incinerators, industrial boilers, and other industrial facilities.
A real-time mercury monitor is an essential tool for understanding and controlling mercury emissions and optimizing mercury control technologies. The 915J Mercury Monitor performs Continuous Emissions Mercury Monitoring for Point Source Emissions (Stacks) derived from the combustion of coal, Portland Cement manufacturing, industrial boilers, municipal incinerators, etc. Years of research and development, extensive testing, and improvements have resulted in an innovative design that focuses on high reliability, low maintenance, ruggedness, ease of use, and flexibility. Industry-leading performance has been demonstrated in dozens of power plants under a variety of challenging conditions.
