GAOTek Desktop PH Indicator
GAO Tek Desktop pH Indicator is an instrument used to measure the pH value of a solution, and the method for measuring the pH value of an acidity meter is a potentiometric method. In addition to measuring the acidity of the solution, it can also measure the electromotive force (mV) of the battery.
Description
Overview
GAO Tek Desktop pH Indicator is an instrument used to measure the pH value of a solution, and the method for measuring the pH value of an acidity meter is a potentiometric method. In addition to measuring the acidity of the solution, it can also measure the electromotive force (mV) of the battery. It is mainly composed of three parts: reference electrode (calomel electrode), indicator electrode (glass electrode) and precision potentiometer. When measuring, the glass electrode is used as the indicating electrode, and the saturated calomel electrode (SCE) is used as the reference electrode to form a battery.
