所述第一试剂为氧化剂，所述第二试剂为缓冲剂，所述第三试剂为显色剂。
假设光源恒定不变，所述实际水样的浊度色度小于预设值，预设 值可以由本领域技术根据实际情况作出限定，在此情况下，ADC数值和色度为线性关系。
准备蒸馏水、第一标准液、第二标准液、第一试剂、第二试剂、第三试剂，上述液体的加入量根据计量器上的红外限位器结合控制器进行计量，加入量已经确定且可计量。蒸馏水浓度为C1＝0mg/L，第一标准液的浓度为C1＝0mg/L的蒸馏水，第二标准液的浓度为C2，单位为mg/L。
在具体实施中，所述根据所述第四测量ADC值和所述第五测量ADC值，获得所述抗干扰因子值，具体通过以下公式计算：
其中，β为所述抗干扰因子值，ADC5为所述第五测量ADC值，ADC4为所述第四测量ADC值。
