Product use

Used to calibrate the accuracy of the pH instrument. To ensure the measurement accuracy of the pH instrument, as the experiment time is prolonged, the test results will shift, so the pH instrument should be calibrated regularly during the experiment.

Preparation Method:

Pour the pH buffer agent into a 250ml volumetric flask.

Dissolve with an appropriate amount of deionized water (carbon dioxide-free), rinse the packaging, and add to the volumetric flask.

Dilute to 250ml with deionized water, ensuring complete dissolution, and it's ready for use. (Note: Stirring with a glass rod can aid dissolution of powders).

Instructions: The pH buffer solution is ready to use directly. Refer to the pH meter's calibration procedure for specific usage instructions. Contact customer service for any questions.

Regular Use (Continuous Monitoring):

If the pH meter is continuously powered on and monitoring pH values (i.e., long-term monitoring), it should be calibrated approximately once a week.

Infrequent Use:

If the pH meter is used infrequently, it should be calibrated once every 2-3 months.

Irregular pH Measurement:

When the pH meter is used for irregular pH measurements, it should be calibrated before each measurement.

Electrode Replacement:

After replacing the electrode of the pH meter, the new electrode should be calibrated.
