ABSTRACT:
A sulfuric acid concentration sensor including a sensor body comprising a high molecular compound having a property to react with sulfuric acid and a property to change an electric conductivity in such a way as one-valued function with a change in sulfuric acid concentration, in which an electric current is flown through the sensor body impregnated in sulfuric acid solution to obtain the electric conductivity of sensor body so as to know the sulfuric acid concentration. Since the electric conductivity of high molecular compound changes corresponding to the sulfuric acid concentration, the sulfuric acid concentration can be known when the electric conductivity of the sensor body i.e. the high molecular compound is obtained, so that the concentration of sulfuric acid can be measured easily.
