Bluelab pH 4.0 Calibration Solution – pH 4.0 calibration solutions – a must in every grower’s toolbox!
Calibrating your pH pen or probe will ensure accurate readings. To get the best from your pH product, we recommend calibrating once a month.
Calibrating your pH pen or probe is required:
- Before first use
- If the calibration reminder has disappeared from the LCD screen (30 days after first calibration)
- If the pH measurement is different from what you expected
- After cleaning and hydration
- After changing the batteries
pH products should always be calibrated to 2 points using fresh pH 7 and pH 4 solutions. If your readings will be higher than pH 7, you can use pH 7 and pH 10 solutions.
