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 ...

While there are a variety of other variables and protocols to be followed to ensure our food supply remains safe, a basic understanding of pH and how it is measured is crucial to food production.

Which pH meters are best? There are numerous reasons you may want a pH meter. Maybe you just bought a new hot tub, plan on starting a hydroponic garden or want to test your drinking water to ensure it ...

The number of samples to analyze, the sample matrix, and the concentration range of the sample decide the choice of the procedure. To quantify samples with an unknown or complex matrix, the standard ...

Ion selective electrodes, also known as ion electrodes, are electrodes that react to specific ions in an aqueous solution. Although a pH-sensitive glass electrode can be considered as a hydrogen ion ...

Although the known photometric techniques for the calculation of ammonia are accurate, they take up a substantial amount of time (Nessler technique 30 min, indophenol technique 90 min reaction time).

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 ...
