We offer an innovative range of opacity, dust, particulate and smoke monitors to suit a variety of continuous emission applications such as boilers, filter bag houses, incinerators and other industrial and marine processes.

From our large modern facility in rural Oxfordshire, we design and manufacture all our own products. We export worldwide to more than 40 countries, either through our network of local distributors or directly from our offices here in the UK.

Engineered for accuracy and performance, our instruments are of rugged design and have an excellent reliability record, which has seen them become the industry standard for many large OEM customers.
