The determination of pH is one of the most common process chemical measurements made today. This booklet explains the principles behind the measurement and discusses ways of avoiding common pitfalls. The booklet also discusses industrial ORP (oxidation-reduction potential) measurements.
tal for a meaningful pH measurement. Accordingly, both practical and theoretical requirements are discussed in depth so that the measuring principle is understood and an accurate measurement made possible. The first section (practical considerations) of the book describes the sensor, and the other elements that constitute a pH measurement sys-tem.
The Theory of pH Measurement. pH measurement has a wide variety of industrial applications in virtually every industry. These range from water conditioning to specific process related measurements to waste treatment. WHAT IS pH? pH is a measure of the acidity or alkalinity of a water solution.
1 Ιαν 2002 · methods for measuring pH and the rationale for the assignment of pH values with appropriate uncertainties to selected primary and secondary substances. CONTENTS
6 ημέρες πριν · In this comprehensive guide, we’ll explore various water pH methods, techniques for measuring pH, and the significance of pH in different types of water and solutions. Understanding pH. pH is a measure of the acidity or basicity of a solution, ranging from 0 (most acidic) to 14 (most basic), with 7 being neutral.
The aim of this book is to give a representative description of pH measurement in the process industries. The actual sensor, the pH electrode, is therefore the main focus of the text. Correct sensor use is fundamental for a meaningful pH measurement.
To be able to measure pH one needs to have a measurement tool which is sensitive to the hydrogen ions that define the pH value. The principle of the measurement is that one takes a sensor with a glass membrane which is sensitive to hydrogen ions and observes the reaction between it and a sample solution.
