CT-1003PH composite pH electrode is composed of pH glass electrode and silver-silver chloride reference electrode. The shell is made of acid, alkali and high temperature resistant glass, which can work continuously for 24 hours. It is the key measurement component of the pH meter, used to measure the pH value of the hydrogen ion depth in the aqueous solution, widely used in the pH detection of chemical industry, pharmaceutical industry and scientific research.
When the pH electrode is used for the first time or left unused for a long time, soak the electrode ball in 3.3N potassium chloride solution to activate it for 2 hours.
When measuring, it should be washed in distilled water first, and wiped dry with filter paper to prevent impurities from being brought in. The electrode bulb and junction should be immersed in the measured solution at the same time.
CT-1003pH compound electrode does not need to add external reference solution.
For CT-1003C pH composite electrode, 3.3N KCL external reference solution must be added.
