SUP-ADS-V300 Oil-in-Water Sensor

The oil-in-water sensor is a specialized instrument designed for detecting the concentration of oil contaminants in water. It operates based on an optical principle, primarily UV fluorescence, enabling rapid and continuous online monitoring. Equipped with an integrated self-cleaning brush, the sensor effectively removes bubbles and oil residues, reducing fouling interference and extending maintenance intervals, ensuring excellent long-term stability. It supports effective monitoring and early warning of oil pollution in water.
