| Abstract: | The on line pH measurement of liquor has been applied abroad in the department of the electric power and the chemistry.It is an important parameter to scale the acidity and basicity of liquor.Through the on-line continual pH measurement,the acidity and basicity of water can be controlled within a preconcerted range and the erodation and the fabrication of the instrument are depreciated.But the temperature is the major factor to affect the measurement accuracy.To deduce the error,in this article,according to the character of the double function and small volume of semiconductor refrigeration and we put a pH pole in the small constant temperature system.By this means the fluctuation of temperature will be faint,so the measurement accuracy of the instrument is improved. |
