Your online guide to
pH measurement

The objective of this site is to explain everything you need to know about pH measurement.

I had the pleasure in my previous job to give courses in this area of measurement techniques. It was fun and I met many nice people. One thing I found out was that most people appreciate a simple and a less scientific approach, regardless of level of education. My hope is that I have succeeded to include this insight when I built this site.


Why measure pH?

• It is a critical measurement in industries ranging from chemical processing, pulp and paper, food and beverage and biotechnology.

• To test a chemical against a specification. To ensure product quality.

• To test a sample against a legal requirement.

• It is of outstanding importance in water and environmental analysis.

• Prevent damage to materials and humans.

Feedback from readers:


This site is really helpful, thanks for posting this. I really like how each topic is linked at the end to another page.

I have started working at a water treatment plant (lots of probes of different kinds) and have a science background, but did not learn this in huge detail at uni unfortunately. Very helpful to know! Thanks!
