Patent ID: 8221597

Claim:
A pH adjusting apparatus comprising: an electrolytic chip which receives a solution whose pH is to be adjusted, the electrolytic chip comprising: an enclosed chamber including a cathode at a side of the chamber and an anode at an opposite side of the chamber, and in which the pH of the solution is adjusted; an ion-exchange material which divides the enclosed chamber into a cathode chamber comprising the cathode and an anode chamber comprising the anode; and an anode support between the anode and the ion-exchange material; an electrolytic chip loading station that receives the electrolytic chip; an input unit that inputs electrolysis conditions; a control unit which receives the electrolysis conditions from the input unit and controls electrolysis in the electrolytic chip, a current measurement unit which measures a current applied to the electrolytic chip and transmits the measured current to the control unit, wherein the control unit applies a constant current to the chamber of the electrolytic chip based on the current measured by the current measurement unit; and a display unit that displays the electrolysis conditions and a progress of the electrolysis.
