Environmental Monitor Service, Inc. was founded by James F. Cognetta who offers over 40 years in the opacity and dust monitor industry. As a former Owner/Vice-president of Dynatron, Inc., he was with the company from its inception in 1972 until its sale in 1989. He along with his partners pioneered many of the technology that is still used today in the opacity and dust monitor industry.

In 1990, Mr. Cognetta took his knowledge and expertise gained during these years to his new company, Environmental Monitor Service. His vision was to provide his customers with the highest level of reliability, service and support. Through his hard work and dedication, EMS has become synonymous with quality, dependable opacity and dust monitors as well as factory and field service which is second to none.

In 2010 Mr. Cognetta announced that the company would begin its transition to the second generation and handed many of his responsibilities over to his stepson Robert Zembruski. James will remain instrumental in engineering and development of new products. We look forward to continued growth and new product development in the near future.
