MDR-3200-COD COD在线分析仪

MDR-3200-COD COD在线分析仪具有反应快速、测量精准、安装方便、无需试剂等特点。采用两路光源，一路紫外光用于测量水中COD含量，一路参比光用于测量水体浊度，另外通过特定算法对光路衰减进行补偿并可在一定程度上消除颗粒状悬浮物杂质的干扰，从而实现更加稳定可靠的测量。

    MDR-3200-COD COD online analyzer has the characteristics of fast reaction, accurate measurement, easy installation and no reagents. Two light sources are used, one ultraviolet light is used to measure COD content in water, and one reference light is used to measure turbidity in water. In addition, a specific algorithm is used to compensate the attenuation of optical path and eliminate the interference of particulate suspended impurities to a certain extent, so as to achieve more stable and reliable measurement.
