Note: Thus, Spectral Absorption Co-efficient 245nm corresponds as sum parameter for the inorganic salt contamination in approximate electrical conductivity. A number of organic substances absorb ultraviolet light. It is based on DIN 38404-3 (2006), which enables measurement at a wavelength of 254 nm. The light attenuation per meter of water (hence the dimension 1 / m) simultaneously functions as a measure of organic contamination of the water. Thus, it is also possible to convert the measured value into approximately related carbon parameters such as TOC (Total Organic Carbon), COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand).
