KOI300 online water oil analyzer is an online water quality analyzer based on OSA optical water quality analysis platform. In an integrated design, high brightness UV leds of a specific wavelength excite the Polycyclic aromatic hydrocarbon to make them fluoresce, and high sensitivity photoelectric analyzers capture weak fluorescence signals that can be converted into oil concentrations in water. Digital, intelligent analyzer design concept, can automatically compensate for voltage fluctuations, device aging, temperature changes on the impact of measured values. RS485 signal output, easy networking and system integration, widely used in surface water, pollution sources and other industries.
