Continuous emissions monitoring system

A Continuous Emissions Monitoring System (CEMS) is a piece of equipment that measures the amount of pollution coming out of something like a factory. It literally monitors the air around the factory all the time and reports back how much pollution is being released. CEMS helps people understand how much pollution is going into the environment and helps protect people from getting sick from air pollution. The equipment is constantly looking for things like smoke, dust, and other smelly gases so it can alert workers if something is not safe.
