Most pH applications are in the 2.5 to 12.5 pH range. The pHD Differential pH sensor with the
wide-range glass process electrode operates very well in this range. Some industrial
applications require accurate measurement and control below 2 or above 12 pH. In these
special cases, please contact the manufacturer for further details.
