This paper is written to help those who are looking to engineer the installation of a new pH loop, have a new loop ready for installation or are re-doing an existing loop. Whether a novice to the world of pH or a seasoned veteran, this is intended to be a helpful roadmap to a successful journey. It is not an end all be all, but rather a primer to get you past the most common road blocks.
Maybe you have heard past pH horror stories throughout chemical, food and water treatment plants. And yes, the stories are mostly true. If you haven’t heard any of these stories, maybe this list will keep you from adding your own story to the already toppling heap. If you are at all familiar with pH measurement, you probably know the horror stories, and maybe even have had your own experiences.
When we conduct pH seminars or schools, one question we ask the group is, “How many of you have worked with pH?, raise your hands. Now keep them up. How many of you have had bad experiences with pH?, keep your hands up”. How many hands do you think went down? You guessed it, the majority of hands remained high and somewhat shy.
