Description
pH electrodes must be calibrated regularly; at least once a day prior to measurements and after every cleaning, regeneration or long-term storage. The calibration adjusts slope and offset of an electrode to their true values. Since an electrode is characterized by both its slope and its offset, it is advisable to do a minimum of a two point calibration for reliable measurements and better precision. It is important is that the measurements are within the calibration range.
The internationally recognized pH scale is based on standard reference materials (SRM) selected by NIST (National Institute of Standards and Technology, USA). These buffer solutions are traceable to these primary standards. The quality inspection certificate, that is available for every bottle and sachet, guarantees stated values and traceability.
