Overview

The QIWEI PHS-3E pH meter is a Benchtop microcomputer pH Meter with a wide Measurement range, covering -2 to 18pH. The instrument uses a glass electrode made of a special sensitive film for high Sensitivity, Data storage and extraction functions, automatic temperature compensation, easy operation, stable and reliable measurement data.

Features

Measurement range is wide, covering -2 to 18pH. 2. Glass electrode made of special sensitive film with high Sensitivity. 3. Data storage and extraction functions. 4. Can automatically perform temperature compensation. 5. Easy and simple operation, stable measurement data.

Principle

Glass electrode is used as the indicator Electrode, and its potential varies with the concentration and temperature of hydrogen ions in the measured solution. The reference Electrode (usually Calomel electrode) potential remains stable. When the pH value of the solution changes, the potential difference between the two Electrodes changes, and the relationship is in accordance with a specific formula (Delta E = -58.16 × Delta pH × (273 + t ℃)/293). The measurement of the pH value is essentially the measurement of the potential difference. The PHS-3E pH meter is equipped with a composite Electrode composed of Glass electrode and Ag-Agcl Electrode, and its zero potential pH value is 7 +/- 0.25 pH.
