Calibration solutions are used to calibrate the pH probe. These are liquids which are manufactured specific to the calibration process. It is recommended a two point calibration of pH is done to ensure the most reliable results.
pH calibration solutions are available in pH 7.0, pH 4.0 and pH 10.0
-
If a pH below 7.0 is being measured, use pH 7.0 and pH 4.0 calibration solutions.
-
If a pH above 7.0 is being measured, use pH 7.0 and pH 10.0 calibration solutions.
Calibration Solutions should be stored in a cool place out of direct sun and heat. Please keep out of reach of children. They should be stored with the lids securely tightened. Contamination between solutions can easily occur, which will affect the validity of the calibration. We recommend that the solutions are de-cantered into a smaller vessel and the contents discarded when the calibration process has been completed.
