Bluelab Buffer 4 & Buffer 7
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.
