Doctor Days


The focus is on the essentials of practical pH and dissolved oxygen measurement. Dissolved oxygen and pH are some of the most common and routine types of analyses, but in order to achieve good precision and accuracy, proper technique must be followed.

We've added a NEW segment on optical measurements, a discussion on theory, and how optical measurements benefit your R&D and process operations.
