Abstract
PURPOSE:A transmission window is provided at the mid-point of one of the optical paths of a turbidity meter having two systems of optical paths for transmission of light through the liquid being measured, whereby the effect of contaminated window surface is eliminated and contimuous measurement of turbidity can be made at high accuracy.
