Hach calibration pH Buffers are required for fast and reliable pH determination in laboratory and field analysis. pH Buffers provide pH electrode calibration in different ranges with an accuracy of ±0.02 pH at the temperature of 25 °C. The product is available in volumes from 15mL to 20L. Hach pH Buffer Standard Solutions are available in bottles, single-use pouches (singlets) and Bag-in-boxes (BiB). All pH Buffers are colour-coded or colourless solutions traceable to IUPAC and NIST standard reference materials.
