Description
Summary:The operating principle and composition of the VNIIFTRI coulometric device is based on a three-chamber electrochemical cell of vertical construction that is part of the set of primary state standards for the pH scale and indices of pX ion indices. Metrological characteristics of the device ensure reproducibility of pH in the standard with an error of not more than 0.003 in the range of pH = 1.0–12, and this corresponds to the best world analogs.
