2024-07-11 21:51:02 In the case of low demand, you can use neutral standard buffer solution (7.0) for calibration, which is called single-point calibration and is used to confirm the actual zero point of the pH probe. At this point, the slope is the theoretical value. Then the actual slope of the pH probe can be confirmed by calibration with standard buffer solution (4.0) after signal-point calibration. Therefore, in order to ensure the measurement accuracy, it is recommended to use two-point calibration. Tonny12138
