Abstract
PURPOSE: To perform the calibration immediately and to reduce the cost, time and labor by dipping the measuring electrode in the pH standard solution directly.
CONSTITUTION: The method is characterized by the process such that the hydrogencarbonate ion solution 6 is fed to the gas permeable tube 5 that is put into the liquid to be tested or gas to be tested 4 and the pH of the solution 8 from the tube 5 is measured to convert itself into the concentration of carbonic acid gas. An output of the pH electrode 1 is sent to the antilogarithm converter 10 through the high input impedance volt meter 9. After this, it is converted into the concentration of carbonic acid gas by the linear meter 11 and is read. In the case of measuring carbonic acid gas, when the capacity concentration of carbonic acid gas in the tested material is about 10%, the pH is on the order of 6.61, and is on the order of 7.1 to about 1% concentration. The calibration is performed by using a standard solution of pH 6.61 so that the linear meter 11 indicates about 10% concentration.
