Our wide range of pH meters, an essential laboratory and industrial instrument designed to measure the acidity or alkalinity of a solution. It does this by assessing the concentration of hydrogen ions in the liquid, which is represented on a logarithmic pH scale ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral. Typically consisting of a probe with a glass electrode that is sensitive to pH changes and a reference electrode, pH meters offer precise and rapid pH readings.
