The 101 of pH measurement (from a practical point of view)

Portable pH and conductivity meter used to measure water

Metrohm is pleased to present an Application Bulletin presenting the basics of pH measurement.

As this Bulletin is intended for practical use, the theoretical aspects (that can be found in numerous textbooks and publications) are treated only briefly.

> AB-188 pH measurement technique



Starting with prerequisites such as electrode calibration, reagents needed, and potential error sources on the side of the hardware (diaphragm, gel layer and response behavior), the bulletin continues to explain how to conduct an electrode test, various aspects of appropriate electrode care.

It ends with an outlook at pH measurement in different media and a list of references where to find more information on pH measurement.
