Measurement principle
Light, from a light source lamp passes through the sample cell, is split into two directions using a half-mirror. The amounts of transmitted UV and visible light are detected by photocells. Part of the light from the lamp directly enters a photocell on the light source side, and the amounts of radiated UV and visible light are detected. By processing these four detection signals, it is possible to measure turbidity-corrected UV absorbance (UV-VIS) with automatic correction for the effects of changes in the turbidity of the sample water and changes in the emission intensity of the light source lamp.
