RK500-26 BOD (Biochemical Oxygen Demand) Sensor
◆ RK500-26 BOD sensor is based on ultraviolet method and compensates the attenuation of optical path through specific algorithm. It can eliminate the interference of particulate suspended matter impurities in the measurement results to a certain extent, making the measurement results more stable and reliable.
► Most organic compounds dissolved in water have absorption properties for ultraviolet rays. Therefore, by measuring the degree to which these organic compounds absorb ultraviolet radiation, the content of dissolved organic pollutants in water can be accurately measured.
FEATURES:
● No reagent, no pollution, more economic and environmental
protection
