摘要
An apparatus is provided to maintain the concentration of an aqueous solution constantly by detecting the concentration of the aqueous solution in real time through a sensor attached to a tank to control the operation of a pump. An apparatus for automatically controlling the concentration of solution comprises a sensor which is able to read the concentration of an aqueous solution into electric current and resistance value, a pump which supplies an original solution, an circuit plate in which a microprocessor capable of controlling the operation of the pump by the electric current and the resistance value input from the sensor.
