ABSTRACT:
A device for measuring particles in a liquid, utilizing a light source for the illumination of two detectors, one through a relatively short distance and the other through a relatively long distance, with liquid to be measured passing between the light source and the two detectors. A reference signal produced by the first cell is supplied to an amplifier and indicator, and a measurement signal produced by the second detector is supplied to the amplifier and indicator, with such amplifier and indicator producing a visual indication of the concentration of particles suspended in the liquid. The two detectors and light source are contained in a small housing, remote from the amplifier and indicator, and connected to it by a flexible cable.
