measurementprinciplePrinciple

The online analyzer for organic compounds using spectroscopy is based on the absorption of ultraviolet light by organic compounds254nmSpectral absorption coefficientSAC254An important measurement parameter for the content of soluble organic matter in reaction water, which can be converted into under certain conditionsCOD/BOD value. This method can achieve continuous monitoring without the need for any reagents.
