Products Description
The pH value of aqueous solution is generally measured with glass electrode as the indicator electrode and calomel electrode as the reference electrode. When the pH value of the solution changes, the potential generated between the glass electrode and the calomel electrode also changes, and the potential change relationship conforms to the following formula:
△E＝－58.16×△pH×(273+t℃)/293（mV）
Can be widely used in chemical, metallurgy, environmental protection, biochemistry, food and tap water and other solutions PH monitoring.
Product characteristics
- E201 composite electrode, fast reaction, good stability.
- Stable performance, reliable, simple operation.
- Suitable for precise measurement of acidity (pH) of solution in laboratory, widely used in electrochemical analysis of light industry, chemical industry, food, environmental protection, education and scientific research departments.
