5.4 pH Measurement

5.4.1 Calibration Preparation

- The electrode slope and zero potential of pH electrodes drift slightly over time. To accurately measure pH, it is recommended to calibrate the pH electrode before use, the instrument supports 1-5 points calibration.
- One point calibration is a calibration process with a single standard solution, commonly applied in a quick test. The calibration slope is 100% in here.
- Two-point calibration is to use two pH standard buffer solutions to calibrate the electrode, and construct a linear calibration curve through two points. Two-point calibration is the most commonly used calibration method, and it is usually recommended that the pH value of the solution to be measured lies between the two standard buffer solutions. Two-point calibration can improve pH measurement accuracy.
- Multi-point calibration is a calibration process with more than one standard solution. It is recommended to calibrate between two standard buffer solutions at the pH of the solution to be tested. Multi-point calibration covers a wider measurement range for accurate pH measurement. Before starting calibration, please prepare one or more pH standard buffer solutions.

5.4.2 Standards group selection

Before starting calibration, please prepare one or more pH standard buffer solutions. The meter has standards recognition function. Please set the Standard Group before the measurement.
You can also set the identification type to "Manual Mode" and manually enter the nominal value during the calibration process.
