Product Overview

The commonly used methods for detecting oil in water include suspension method, infrared spectrophotometry (not suitable for low range), ultraviolet spectrophotometry (not suitable for high range), etc. Lunhan's online oil sensor in water adopts the principle of fluorescence method. Compared with several commonly used methods, fluorescence method is more efficient, fast, and has good repeatability, and can be monitored in real-time online. Sensors have better repeatability and stability. Equipped with an automatic cleaning brush, it can eliminate bubbles, reduce the impact of contamination on measurement, prolong maintenance cycles, and maintain stability even during long-term online use. It can serve as a warning for oil pollution in water.

Product Principle

Using ultraviolet fluorescence method to monitor the oil content in water, the concentration of oil in the water is quantitatively analyzed based on the fluorescence intensity emitted by petroleum and its aromatic compounds and conjugated double bond compounds after absorbing ultraviolet light. Aromatic hydrocarbons in petroleum can produce fluorescence under ultraviolet light excitation, and the value of oil in water can be calculated based on the intensity of fluorescence.
