Why is my bluelab Measuring Instruments pH reading inaccurate?
- AAndre FranklinAug 26, 2025
An inaccurate pH reading on your Bluelab Measuring Instruments can stem from several reasons. The probe might be contaminated, in which case you should clean the pH probe. If cleaning doesn't resolve the issue, consider replacing the probe. Ensure you allow sufficient time for the reading to stabilize before calibration. Another cause might be that you are using the factory default calibration or the calibration is old, so you should calibrate the pH probe.
