-Typical applications include industrial circulating water, condensate, wastewater treatment, surface water station and other water quality monitoring. Working principle UV fluorescence analysis is a very sensitive method, which can determine the concentration of polycyclic aromatic hydrocarbons in water, and has a strong correlation with the oil content in water. What is measured is the intensity of radiation from the water sample, which can absorb light at shorter wavelengths and emit light (fluorescence) at longer wavelengths. Different types of oil have different radiation characteristics. FP360sc is a UV fluorescent photometer with stable operation. Miniature design and long-term stability, making it very suitable for aromatic carbon in industrial applications
