Proof: Certifications, Patents & Field Results
Quick Answer
What evidence backs up Halogen's chlorine analyzer claims?
Certifications & compliance
NSF/ANSI 61
Certified for direct contact with drinking water — the only amperometric chlorine sensor certified for in-pipe (wet-tap) installation.
NSF/ANSI 372
Lead-free compliance for drinking water system components.
EPA Method 334.0
Compliant for continuous online chlorine residual monitoring and regulatory reporting.
BABA / Build America, Buy America
Eligible for federally funded U.S. water infrastructure projects.
Patented technology
Halogen Systems holds 11 patents across the US, EU, Korea, China, and Germany covering its bare-electrode amperometric sensor, the SensiCLENE™ self-cleaning system, and multiparameter measurement. The core technology originated from a U.S. Office of Naval Research (Navy SBIR) program and has been commercialized for municipal drinking water, distribution, Legionella control, and maritime applications.

The MP5 measures free chlorine to ±5% of reading or 0.02 mg/L. In an independent five-month evaluation at a Wessex Water (UK) treatment works, it ran with zero calibration, zero cleaning, and zero maintenance — and revealed that the incumbent sensor had been driving chronic chlorine over-dosing of 10.67% per operational cycle. A published 65-day study documents the MP5's stability against sensors that drift over the same window.

Frequently asked questions
Is the Halogen MP5 certified for drinking water?
Yes. The MP5 is certified to NSF/ANSI 61 and NSF/ANSI 372 for direct contact with drinking water, and it is the only amperometric chlorine sensor certified for direct in-pipe (wet-tap) installation. It is also EPA Method 334.0 compliant for regulatory reporting and BABA compliant for federally funded projects.
How many patents does Halogen Systems hold?
Halogen Systems holds 11 patents across the US, EU, Korea, China, and Germany covering its bare-electrode amperometric sensor, the SensiCLENE self-cleaning system, and multiparameter measurement. The technology originated from a U.S. Office of Naval Research (Navy SBIR) program.
Has the MP5 been independently validated?
Yes. In a five-month independent evaluation at a Wessex Water (UK) treatment works, the MP5 ran with zero calibration, zero cleaning, and zero maintenance while revealing that the incumbent sensor had been driving chronic chlorine over-dosing of 10.67% per cycle. Utilities including Lakewood, Orange County, Iron Bridge, Palm Beach County, and Maui have documented similar field results.
How accurate is the MP5?
The MP5 measures free chlorine to ±5% of reading or 0.02 mg/L. In the City of Lakewood pilot it held within 0.04 ppm of the reference method with zero calibration over six months, and a published 65-day study documents its stability against sensors that drift over the same period.
