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 — an 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
Selected patent records document amperometric sensing, self-cleaning and multiparameter measurement. The patent reference page explains the counting scope and distinguishes related international records. 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.

MP-5F specification: free chlorine to ±5% of reference-calibrated value or 0.06 ppm, whichever is greater. In an independent five-month evaluation at a Wessex Water (UK) treatment works, the original MP5 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 MP-5F certified for drinking water?
Yes. The MP-5F is certified to NSF/ANSI 61 and NSF/ANSI 372 for direct contact with drinking water, and it is an 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.
Where can I verify Halogen sensor patents?
The patent reference page distinguishes selected U.S. sensor grants, international counterparts and the founder’s career invention record. Consult each record for scope and status. 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 (current model: MP-5F) 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 MP-5F?
MP-5F specification: free chlorine to ±5% of reference-calibrated value or 0.06 ppm, whichever is greater. In the City of Lakewood pilot, the original MP5 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.
