Determination of pH value. Technical buffer solutions for the calibration of technical measuring installationsWhat is ISO 23497 technical buffer solution pH about? A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. ISO 23497 specifies requirements for technical buffer solutions. These buffer solutions are preferably used for the calibration and adjustment of
