Apparatus for automatically counting the microorganisms possibly present in liquids, particularly in waters for human use.

摘要

An apparatus for automatically counting the microorganisms possibly present in liquids, particularly in waters for human use, comprising in combination at least one device intended to mix the liquid to be analyzed, for example waters for human use, with a suitable reagent; at least one device adapted to mix control water with the reagent used for analyzing the liquid to be analyzed; at least one measuring cell provided with a sensor for detecting the bacterial charge possibly present in the liquid and carrying out the measurement thereof; at least one control cell provided with a sensor for detecting the presence of bacteria in the control water; two or more automatic sterilizing and washing devices each adapted to reset a measurement or a control cell associated thereto to allow the successive analysis to be carried out; a thermostatic device associated to the cells of the apparatus adapted to keep the cells at a constant predetermined temperature; an input and output data control system for controlling the necessary automatic operations of the apparatus; and, a data transmission system for feeding the information obtained on the bacterial charge of waters and the machine operation to a control center and possibly receiving therefrom the directives for any successive operation.
