Lovibond’s color-coded pH buffer solutions are suitable for calibrating pH electrodes with all types of pH meters, whether using automatic buffer recognition or manually adjustable pH values. Only standard reference materials traceable to NIST are used for production. The practical two-neck dosing bottle can be used either as a calibration vessel or as a measuring cup. This keeps the buffer solution fresh and free of contamination even after multiple use.
