Abstract
PURPOSE: To measure the concentration of a liquid easily and swiftly through the electrode, by forming a circulation passage and a discharge passage between the measuring cell and the pump, by means of the changeover valve.
CONSTITUTION: The concentration of a liquid in the cell 1 is measured electrically through the electrode which can be attached and detached freely to and from the cell 1. When the changover valve 5 is controlled through the controller 7, a circulation passage to the cell 1 is formed through the pump 4, and a liquid in the cell 1 is stirred. On the other hand, after the measurement has been finished, a liquid discharge passage is formed by the pump 4, the valve 5 and the discharge pipe 10 by changing over the valve 5, a measured liquid is discharged from the cell 1, and therefore the concentration of a liquid can be measured easily and swiftly.
