Why Calibrate Ph Meter?

pH meter calibration is a necessary step of using a pH meter because of how the electrode changes over time. ... Regularly calibrating your pH meter will adjust your electrode based off any changes that may have occurred and ensures that your readings are accurate and repeatable.

What happens if you don't calibrate a pH meter?

Accurate pH measurements cannot be accomplished with a pH meter unless the meter has been calibrated against standardized buffer. Without a proper calibration the meter has no way to determine the pH value of the solution you are testing.

Should you calibrate pH meter?

Calibrate your pH meters often

To optimize your reading accuracy, you need to regularly calibrate your meters to ensure they work with the particular pH electrodes that are attached to them.
