WebbAn electronic pH meter is used to obtain more accurate pH measurements. A pH meter is an instrument used to measure hydrogen ion activity in solutions - in other words, this instrument measures acidity/alkalinity of a solution. The degree of hydrogen ion activity is ultimately expressed as pH level, which generally ranges from 1 to 14. Webb16 mars 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution.
WebbpH meter, electric device used to measure hydrogen-ion activity (acidity or alkalinity) in solution. Fundamentally, a pH meter consists of a voltmeter attached to a pH-responsive electrode and a reference (unvarying) electrode. WebbpH meter calibration is a necessary step of using a pH meter because of how the electrode changes over time. Your pH electrode is designed to measure pH based off of slope and offset (the Nernst Equation ). However because of aging and use, the electrode's performance will stray from the theoretical slope and offset over time.
