ow to Use (Calibration Instructions)

how to use 

• Ensure the pH meter and electrode are clean and in good working condition. Rinse the electrode with distilled or deionized water before use.
• Pour a small amount of the buffer solution into a clean container. Do not insert the electrode directly into the storage bottle to avoid contamination.
• Switch on the pH meter and select the calibration mode according to the manufacturer’s instructions.
• Immerse the electrode into the buffer solution, ensuring the sensing tip is fully covered.
• Allow the reading to stabilize, then confirm or adjust the calibration to match the buffer’s stated pH value (pH 4.00, 7.00, or 10.00).
• Rinse the electrode with distilled water after calibration and repeat the process with the next buffer solution if multi-point calibration is required.
• After use, discard the used buffer solution and tightly close the bottle
