Total chlorine monitoring for chloramine systems
One total chlorine number can hide four very different plants. This guide shows how to see nitrification coming, defend your residual, and choose an analyzer you can afford to keep running.
What's inside
- ✓The chloramine chemistry window — Cl₂:NH₃ ratios, pH, and why a single DPD total reading can’t tell optimal chloramination from a dichloramine problem.
- ✓Nitrification early warning — the signals to watch together (monochloramine vs. total, pH, temperature, conductivity) and what to grab-sample when the trend turns.
- ✓Residual compliance checklist — what your monitoring has to prove, and how online analyzers fit under EPA Method 334.0.
- ✓Why reagent-based analyzers drift and disagree — consumables, species ambiguity, DPD timing and slow refresh.
- ✓Maintenance cost comparison — equipment, reagents, wear parts and waste stream per analyzer, plus a worksheet for your own numbers.
- ✓How MP-Total cleans itself — SensiCLENE captive beads, magnetic drive and controlled flow at the electrode.
- ✓A buyer’s checklist — ten questions to ask any analyzer vendor, and a five-step pilot plan.

Who it's for
Written for utilities that chloraminate or are converting from free chlorine; for teams running online DPD total panels and reagent programs; for sites with nitrification history in warm tanks, long-detention zones and dead ends; and for engineers writing a residual-monitoring spec.
“You had me at mono and free on the same sensor.”— Chloramination plant operator, March 2026
