A long history in design, manufacturing and supporting of environmental monitoring systems.

Our History

Formed in 1997 through a buyout of the continuous emissions monitoring systems (CEMS) division of Enviroplan, Monitoring Solutions is proud to have over 40 years of experience in the CEMS business and a combined total of over 200 years’ experience with our people.

Involved with some of the first dilution and extraction systems ever built, we offer the expertise to make sure our CEMS are the most reliable, accurate and easy to maintain products in the industry today.

Monitoring Solutions specializes in helping industry and government meet rapidly growing demands for air pollution monitoring and reporting due to changing regulatory requirements (i.e. 40CFRPart60 and 40CFRPart75). We provide engineered solutions for process and environmental monitoring and reporting.
