How to calibrate your Bluelab pH products

If you want to improve your Bluelab pH product’s accuracy and longevity, you’ll need to get into the habit of regular cleaning and calibration. Luckily, the easy-to-follow calibration process is the same for all Bluelab pH meters and pens. 

After cleaning your pH probe, you’ll need to calibrate it with pH calibration solutions at two reference standards - 4.0 and 7.0 pH. Once calibrated, you can start measuring pH again immediately. You’ll need to recalibrate whenever you clean your pH probe and when your meter alerts you that a calibration is needed.

High-quality calibration solutions - Effective, affordable pH calibration

Bluelab pH 4.0 Calibration Solution - 500 ml is essential for use with all Bluelab pH products. All Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab products last longer and maintain accuracy.

To complete calibration, remember to stock up on Bluelab pH 7.0 Calibration Solution, which is available in our store.
