Based on the absorption of ultraviolet light by organic matter, spectroscopic organic material online sensor
adopts the 254 nm spectral absorption coefficient SAC254 which is used to reflect the important measurement
parameters of the soluble organic matter content in water, and it can be converted into COD value under
certain conditions. This method allows for continuous monitoring without the need for any reagents.
