Petroleum, as one of the main pollutants, has been included in the list of hazardous waste in China. The National Environmental Protection Administration has included the monitoring of petroleum in water as one of the six mandatory water quality indicators. Petroleum is a mandatory testing item for polluting enterprises in nearly 30 industries and fields. The LUMEX online oil film monitoring instrument uses optical remote sensing technology to determine the presence of floating oil on the water surface based on the difference in vertical light reflectivity between the oil film and the water surface. The measurement data is automatically processed through infrared sensors and a single channel photoelectric receiving system. Multiple sets of online monitor architecture design can be implemented to effectively monitor the impact range and diffusion degree of oil film, oil pollution accidents, and leakage accidents.
