To improve the accuracy and lifespan of the Bluelab pH device, you must get into the habit of cleaning and calibrating it regularly. Calibration is an easy process to perform and is the same for all Bluelab pH meters and pens.

After cleaning the pH probe, you must calibrate it using calibration solutions at two reference standards - 4.0 and 7.0 pH. After calibration, you can immediately start measuring pH again. You must calibrate again whenever you clean the pH probe and when the meter alerts you that calibration is required.
