KCH300 online chlorophyll analyzer is an Online water quality analyzer based on OSA optical water quality analysis platform. Integrated design, specific wavelength of high- brightness LED excited chlorophyll a to make its fluorescence, high-sensitivity photoelectric analyzer will capture the weak fluorescence signal to convert chlorophyll a. 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 and other industries.
