A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...

In coal-fired power plants, measurement and control of pH is critical to the efficient operation of wet flue gas scrubbers. However, harsh process conditions can necessitate frequent cleaning and ...

Procter & Gamble has filed a patent for a pH sensing probe that includes a sensor body, a pH glass electrode, a reference electrode, and a backup pH electrode. The backup electrode can be ...

Systems pH control systems are known by their extreme rangeability and sensitivity, but contact between the measurement electrodes and hostile fluids can cause issues. Case studies of representative ...

In addition to pH, ion, voltage and temperature measurement, the combined 781 pH/Ion Meter also offers an automatic stirrer control, a multi-point calibration with up to nine buffers (pH mode), a ...
