Product Description
Yoesemitech’s online OIW sensor adopts ultraviolet fluorescence method measuring principle. Compared with other methods, the fluorescence method is proven to be more efficient, fast and repeatable. It is widely used in environmental monitoring, analytical chemistry, limnological and oceanographic biology.
The sensor has an integrated cleaning brush, which can automatic clean up air bubbles, debris, and biofilm, therefore reduce the interference of contamination on measurement data, make the maintenance period longer, and maintain excellent stability for long-term online use.
Typical applications include: crude and refined oil detection, leakage control at offshore oil pipelines, monitoring of BTXE and polycyclic aromatic compound in fresh water, industrial and municipal sewage works.
Product Features
