Answer: Mettler-Toledo recommends calibrating the S220 pH meter at least daily, or before each use for critical measurements. For routine laboratory tasks, calibration should occur at least once per working day or whenever accuracy is essential. The frequency may vary based on the application requirements and the stability of your electrodes and measurement conditions.
