All You Need to Know about pH - METTLER TOLEDO

For over 100 years, pH has been measured in practice to determine the acidity or basicity of samples like water. Due to the high reliability, sensitivity, and fast response of this analytical parameter, as well as the relatively low cost of the equipment needed to measure pH, it remains a widely used and crucial measurement parameter in many industries today.  And yet, even though measuring pH in the laboratory is a common analysis, many things can go wrong.

The main goal of the pH guide is to disseminate knowledge and understanding of this analytical technique, which will lead to more accurate and reliable results. The following aspects are covered in the different chapters of the guide:

Informative theory – understand the background

The guide provides all the important basics that are necessary for a good understanding of pH measurement. Furthermore, all the vital factors that influence the measurement and possible sources of errors are discussed.

Sensor selection guide – work with the correct equipment

Choosing the right pH electrode is a crucial factor in obtaining accurate and reliable results. This chapter of the guide takes you one-by-one through all the questions that should be clarified in order to find the perfect products for your application. Further help in sensor selection is provided at:
