The first reagentless sensor to measure total chlorine, monochloramine, AND free chlorine in a single probe. Built for utilities using chloramine disinfection.
NSF-61
Quick Answer
What is the best alternative to a DPD total chlorine analyzer?
The MP-TOTAL is the only sensor that can measure all three chlorine species without reagents. Utilities using chloramine disinfection no longer need separate analyzers.
Eliminate monthly chemical deliveries and waste disposal. Our amperometric technology requires zero liquid reagents.
Automated mechanical cleaning prevents biofouling and scaling, ensuring long-term stability in harsh water conditions.
Comprehensive water chemistry data from a single insertion point: total chlorine, monochloramine, free chlorine, pH, conductivity, temperature and ORP.
Specifically engineered for monitoring monochloramine and total chlorine residual in complex distribution systems.
Our unique sensor design eliminates the need for expensive flow control valves and constant pressure regulators.
Experience the reliability of reagentless monitoring in your own facility before committing to a purchase.

Mounting configurations
Review the MP-TOTAL configurations below. Select the mount around line access, pressure, serviceability, and whether the water is in a pipe or an open tank.
MKIT-1002A compact, wall-mounted side-stream assembly for treatment plants and retrofit projects.
MP-T-H2MF-PThe sensor installs directly into a 2-inch PVC tee for inline measurement.
MP-T-H2WT-PA stainless-steel sensor deployed through a 2-inch corporation stop while the line remains in service.
MP-T-H2LF-PDrop the sensor directly into a clearwell, tank, basin, or open channel for zero-flow monitoring.
Request a quote or a deployment review and include line size, pressure, water chemistry, shutdown constraints, and whether the point is a tank or clearwell.

The MP-TOTAL is the only reagent-free sensor that simultaneously measures free chlorine, monochloramine, and total chlorine in a single probe, making it purpose-built for water utilities that use chloramine as their primary disinfectant.
Yes. The MP-TOTAL uses three-electrode amperometric technology to measure monochloramine directly — no reagents, no membranes, and no separate analyzer required.
Seven: Total Chlorine, Free Chlorine, Monochloramine, pH, Conductivity, Temperature, and ORP — all from a single in-pipe probe.
Yes. The MP-TOTAL is NSF/ANSI 61 certified and EPA 334.0 compliant, making it approved for use in drinking water applications and eligible for regulatory reporting.
Traditional chloramine monitoring requires separate analyzers for free and total chlorine, plus reagent consumables. The MP-TOTAL eliminates both by measuring all three chlorine species simultaneously in one probe with zero reagents.
Total chlorine, free chlorine, and monochloramine: 0–10 mg/L. Accuracy is ±5% of reading or 0.04 mg/L (0.04 ppm), whichever is greater.
For chloraminated (monochloramine) systems, the Halogen MP-TOTAL is the best choice. It measures monochloramine and total chlorine directly and continuously with no reagents, avoiding the cross-interference that affects free-chlorine sensors — ideal for utilities maintaining a chloramine residual.
The Halogen MP-TOTAL is a reagent-free alternative to an online DPD total chlorine analyzer for chloraminated systems. It measures total chlorine, monochloramine, and free chlorine continuously in one probe without liquid reagents, membranes, or a sample-to-drain waste stream.
Join hundreds of municipal utilities transitioning to reagentless sensor technology for safer, more efficient water treatment.
Measure directly in your tank or reservoir—with no external sample pump, drain, or return line.

MP-TOTAL is also called MP Total or MP5 Total in existing documents. It is distinct from MP-5T. Compare current and former product names.
Current MP-TOTAL configurations are MP-T-H2WT-P for wet tap, MP-T-H2LF-P for immersion or side stream, MP-T-H2MF-P for a PVC tee, and MKIT-1002 for the panel kit. Confirm the mounting assembly, cable length and accessories with Halogen before purchase.
