About us

With over 30 years of experience, DynOptic Systems has established itself as a recognised specialist in the design and manufacture of high technology instrumentation for opacity, dust, particulate and smoke monitoring.

Founded in 1979 as an independent electronics design house; a role that DynOptic Systems still fulfils today; the business evolved to become an electronics development company designing circuits and embedded software for leading industry clients. With increasing interest in environmental issues and new international legislation, DynOptic Systems identified a need for cost effective yet reliable continuous emissions monitoring equipment and this lead to the design and manufacture of our own comprehensive range of instrumentation.

Our Philosophy is to provide our customers with a quality, yet affordable, range of opacity, dust and particulate monitors. We believe that this is reflected in not only the durability and reliability of our products but also in our commitment to maintaining a multidiscipline engineering team capable of supporting its customer’s needs.

With in-house manufacturing, assembly, software design and  R&D capabilities, the team has responsibility for all activities from  design conception to final product. As a company with a firm foundation in electronic engineering, we have a flair for research and a track record of turning that research into powerful, marketable products.

Continuing the Company’s tradition in developing new and innovative products, in 2005 Tunnel Sensors was formed, manufacturing a range of air pollution monitoring equipment designed specifically for the tunnel market.

Today DynOptic Systems has three core business activities:

  • Opacity, dust, smoke and particulate continuous emission monitoring equipment
  • Electronics development for client lead projects for design of instrumentation software / hardware for bespoke applications
  • Tunnel atmosphere and gas monitoring under our Tunnel Sensors brand
