Maintaining a pH meter

The pH meter is a precision instrument. Proper use and maintenance are essential to ensure long‑lasting performance. Here are several important points:

• - Before taking a measurement, the pH meter must be calibrated using buffer solutions. If your device can only be calibrated at one point, use the buffer solution closest to your usual measurement range.
• - Avoid contaminating the buffer solution. Never insert the electrode directly into the bottle; pour a small amount into a cup and use that. After calibration, discard the used solution and never pour it back into the bottle.
• - Never touch the electrode if possible, especially not with your fingers. To clean it, use only a soft cloth without scrubbing.
• - For storage, always use a special pH‑meter storage solution.
