摘要： A COD conversion equation holding unit (20) in a computing unit of a COD measuring device holds a COD conversion equation that indicates a relationship between total-absorbance that is linearly combined by multiplying an absorbance value at each of a plurality of wavelengths by a weighting factor and a COD value, and a conversion unit (22) finds a converted COD value by using the COD conversion equation, and outputs the resulting value. Preferably, a COD conversion equation calculation unit (26) calculates a COD conversion equation based upon the relationship between the total absorbent and an actual measured COD value in sample water, and a correlation calculation unit (28) finds a correlation with respect to each of a plurality of COD conversion equations calculated by the COD conversion equation calculation unit (26). In this case, the COD conversion equation holding unit (20) holds the conversion equation having the best correlation among the COD conversion equations calculated by the COD conversion equation calculation unit (26) as a COD conversion equation for the sample water.
摘要翻译： COD测量装置的计算单元中的COD转换方程式保持单元（20）保持COD转换方程，其表示通过将多个波长中的每一个的吸光度值乘以加权的线性组合的总吸光度之间的关系因子和COD值，转换单元（22）通过使用COD转换方程求出转换后的COD值，并输出结果值。优选地，COD转化方程式计算单元（26）基于吸收剂与样品水中的实际测量COD值之间的关系计算COD转化方程，相关计算单元（28）由COD转换方程计算单元（26）计算出的多个COD转换方程。在这种情况下，COD转换方程式保持单元（20）将由COD转换方程计算单元（26）计算出的COD转换方程之间具有最佳相关性的转换方程保持为样本水的COD转换方程。
