product description
E-201 pH composite electrode and E-201C are composed of pH measuring electrode and silver-silver chloride reference electrode. The shell is made of polycarbonate. Hydrogen ion concentration, widely used in the pH value detection of chemical industry, pharmaceutical industry and scientific research.
Features and use and maintenance
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.
E-201 pH composite electrode, no need to add reference solution.
E-201C is a refillable pH composite electrode. If the external reference solution decreases during use, 3.3N KCL external reference solution must be added.
