Abstract

A system for monitoring the alkalinity of a treatment liquid in a treatment tank includes a reaction tank; an indicator burette which drops an indicator into the reaction tank; a reagent burette which drops an acidic reagent into the reaction tank; a probe-type absorptiometer to be inserted into the reaction tank; a measuring device which analyzes the transmittance of a solution detected by the absorptiometer to calculate the alkalinity; a first system that collects the treatment liquid from the treatment tank for storing and supplies the treatment liquid to the reaction tank; a control device which controls the operation of the first system so as to supply the treatment liquid to the reaction tank, outputs a completion signal to the measuring device, and controls a discharge system so as to discharge the treatment liquid in the reaction tank, when the calculation of alkalinity by the measuring device is completed.
