MP5 Multiparameter Chlorine Sensor
MP5-A Multiparameter Free Chlorine Analyzer for Drinking Water
The chlorine analyzer that compensates for pH & temperature — maintenance-free for an entire year.
If you measure free chlorine in your drinking water system and want to save roughly 70,000 gallons of water and thousands of dollars in reagents and labor, you need the MP5-A from Halogen Systems. It’s our most versatile and popular analyzer — powerful, robust, and built to run unattended.
Why you need it
- ✓Compensated for pH & temperature — a true free-chlorine reading even as water chemistry shifts

- ✓Maintenance-free for up to a year — SensiCLENE self-cleaning electrodes and long calibration intervals
- ✓No reagents, no membranes, no waste stream — nothing to dose or replace, nothing sent down the drain
