Product Description

Yoesemitech’s online OIW sensor is based measurement principle of ultraviolet fluorescence method. 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

RS - 485 output, Modbus protocol compatible;

Integrated automatic cleaning brush, eliminating measurement interference ;

Use of unique optical and electronic optical filtering technique eliminates the impact of ambient light on the measurement;

UV LED light source with low power consumption, high stability, low drift and long lifetime;

No affection by particulate matter suspended in water.
