Abstract
An apparatus for directly monitoring microorganisms present in a liquid crises a window glass with one face in contact with the liquid. Near the other face is disposed a TV camera having an optical magnifying system for monitoring the microorganisms. A sample cell or a narrow space is formed on said one side of the window glass for direct introduction of a sample of the liquid. The sample is statically held in the cell even though the liquid is in movement. The sample is purged from the cell by feeding a cleaning fluid thereinto or by vibrating or otherside exerting physical movement on the cell, whereafter a new sample is introduced into the cell. Purging of the sample cleans the cell and is prevents it from being smudged with dregs, dirt or the like included in the liquid.
