PH meter composite electrode AOLILONG E201-9 composite electrode

Introduction to E201-9 composite electrode

E201-9 pH meter composite electrode is the key measurement component of the pH meter. It is composed of a pH glass electrode and a silver-silver chloride reference electrode. The shell is made of polycarbonate. It is used to measure the hydrogen ion concentration in aqueous solutions. PH value, it is widely used in the fields of detecting PH in chemical and light industry, pharmaceutical industry and scientific research.

Specifications

Use, maintenance and precautions

1. When using the E201-9 pH meter composite electrode for the first time or leaving it unused for a long time, soak the electrode ball in 3.3 M potassium chloride solution for 2 hours to activate.

2. When measuring, it should be washed in distilled water and dried with filter paper to prevent impurities from being brought in. The electrode bulb and junction should be immersed in the liquid being measured at the same time.

3. E201-9 pH meter composite electrode does not require the addition of external reference solution.
