Amperometric chlorine measurement for operators
How chlorine sensors actually work, why online and grab results disagree, and how to keep an online residual you can defend. Six short modules, a workbook, a quiz and a certificate.

- ✓Module 4 — why DPD and online readings disagree, and the DPD read timing that fixes most of it
