What Halogen Systems does

Halogen Systems Inc. is a privately held Nevada corporation, spun out in 2012 from a US Navy / Office of Naval Research SBIR research program, that designs and manufactures reagent-free, membrane-free, self-cleaning amperometric chlorine analyzers for drinking water distribution, water reclamation, hot-water building loops, and maritime ballast water treatment. Headquartered in Reno, NV (8985 Double Diamond Pkwy, B10) with 1–10 employees, the company sells the MP-series sensor platform — MP5 Free Chlorine, MP-TOTAL (monochloramine and total chlorine), MP-HOT (up to 80°C for Legionella programs), MP-ORP (pH/ORP), and the Marine TRO sensor — anchored by the patented SensiCLENE mechanical self-cleaning system and HiRes impeller flow-independence technology that together deliver 6–12 month calibration intervals and operation as low as $185/year per sensor. All MP-series units are NSF/ANSI 61 and 372 certified for direct in-pipe (wet-tap) installation in drinking water mains, EPA Method 334.0 compliant, and BABA-compliant for IIJA-funded projects, with DNV-GL, KR, and IECEx marine certifications on the ballast water variant.

The company monetizes primarily through one-time hardware sales of sensors, the D20 multi-channel controller, and connectivity modules (IoT-B cellular, BT-B BLE SmartBox, BT420-BAT Sensus AMI interface), augmented by recurring revenue from SensiCLENE polymer-bead consumables (~$35/year), periodic pH-sensor replacement (~$295 every 1–2 years), factory commissioning, and Halogen Cloud data plans. The go-to-market is enterprise field sales with inside-sales support, a content-driven website featuring a 5-year TCO savings calculator and a 3-question product selector, trade publication features in AWWA Opflow (April 2025) and Water Environment Technology (March 2022), and a 30-day free trial for qualified buyers. Distribution is direct — no reseller network is referenced — with strategic technology integrations into Sensus (Xylem) FlexNet AMI networks routing data into the Xylem Data Lake, and dosing-pump integration with Stenner for rural and small-system turnkey chemical-feed packages. Documented customers and case-study deployments are concentrated in US municipal water utilities (City of Lakewood CA, County of Maui, City of Gainesville GA, Orange County FL, Palm Beach County FL, Iron Bridge Regional WRF Orlando), with 500+ sensors deployed worldwide and Palm Beach County actively replacing its entire Hach CL-17 fleet with 50+ MP5 units county-wide.

Core offering

Halogen Systems designs, manufactures, and sells reagent-free, self-cleaning amperometric chlorine analyzers (the MP-series: MP5, MP-TOTAL, MP-HOT, MP-ORP, and Marine TRO) along with supporting hardware including the D20 multi-channel controller, IoT-B cellular telemetry module, and Sensus AMI / BLE SmartBox interfaces. The sensors measure free chlorine, pH, ORP, conductivity, and temperature from a single NSF/ANSI 61-certified in-pipe probe, eliminating the reagents, membranes, and chemical waste stream of conventional DPD analyzers. The portfolio is targeted at municipal drinking water utilities, commercial/institutional buildings requiring Legionella hot-water monitoring, maritime ballast water compliance, and remote off-grid water quality sites.

Product overview

Halogen Systems offers a portfolio of reagent-free, self-cleaning amperometric water quality sensors and supporting infrastructure. The core product line centers on the MP-series multiparameter sensors — the MP5 Free Chlorine (5 parameters: Cl₂, pH, ORP, conductivity, temperature), MP-TOTAL (for chloraminated systems measuring free chlorine, monochloramine, and total chlorine), MP-HOT (for hot water/Legionella monitoring up to 80°C), MP-ORP (pH and ORP), and the Marine TRO sensor (ballast water compliance). These sensors share the company's patented SensiCLENE self-cleaning bare-electrode technology and NSF/ANSI 61 certification for direct in-pipe installation. The D20 Controller is the central display and communication hub — it connects to any MP-series sensor and adds connectivity options including 4-20 mA, Modbus RTU/TCP, BACnet, EtherNet/IP, and cellular LTE-M/NB-IoT. Connectivity is extended further through dedicated modules: the IoT-B cellular modem, the BT420-BAT Sensus AMI interface (for Sensus FlexNet integration and Xylem Data Lake), and the BT-B BLE SmartBox for third-party IoT integrations. Halogen Cloud provides the cloud dashboard layer. The product ecosystem is designed around eliminating the reagents, membranes, waste streams, and frequent maintenance of legacy DPD and membrane-based analyzers.

Partnerships

Four partnerships are on record, tiered core and foundational.

• Sensus (Xylem)coreTechnology or IntegrationSensus FlexNet AMI network integration enabling Halogen MP5 sensor data to transmit alongside meter reads to the Xylem Data Lake dashboard. Halogen Interface Module connects directly to Sensus Smart Gateways, transmitting real-time water quality data (chlorine, pH, conductivity, temperature) over the existing AMI network with no additional communication infrastructure. Deployed at Orange County FL and Gainesville GA for demand-based flushing applications. Each Interface Module supports two Smart Gateways.
• NSF InternationalcoreOthersNSF International provides annual testing and certification of Halogen MP-series sensors to NSF/ANSI 61 and 372 standards for drinking water contact materials. NSF International is an independent, accredited testing body that evaluates and renews Halogen's certifications annually.
• StennercoreTechnology or IntegrationStenner peristaltic pump and tank systems are integrated with Halogen analyzers for rural water system chemical dosing applications. The S 4-20 mA controlled dosing pump (Stenner S Series pump head) is driven by the Halogen analyzer's 4-20 mA signal for precise, variable-speed chemical injection proportional to water demand. Pre-assembled HDPE tanks (7.5–30 gal) with UV-resistant, child-safe lids are offered as part of the rural water system solution.
• U.S. Navy / ONR (Office of Naval Research)foundationalStrategic or Co-development PartnerHalogen Systems was spun out of a US Navy / ONR SBIR (Small Business Innovation Research) research program in 2012 to develop the next generation of compact, reagent-free water quality sensors for shipboard and shore-based water systems. The core technology — bare-electrode amperometric sensing, self-cleaning, and flow independence — originated from this government research program.

• YSI (Xylem): Xylem brand manufacturing water quality instruments including chlorine sensors and the EXO series sondes; competes in the same municipal drinking water customer base and aligns via the Sensus/Xylem AMI channel partnership.
• Electro-Chemical Devices (ECD): Manufactures reagent-free amperometric chlorine analyzers (e.g., ECS series) for municipal and industrial water treatment — the closest direct product competitor to Halogen's reagent-free MP-series.
• Wallace & Tiernan (Veolia): Veolia-owned brand producing chlorination systems and online chlorine analyzers (De Nora/Jesco legacy products), directly competing for municipal disinfection monitoring budgets.

Broad incumbents

• Endress+Hauser: Global process instrumentation leader offering amperometric chlorine sensors (e.g., Memosens CCS51E) within a broad portfolio targeting municipal and industrial water and wastewater customers.
• Yokogawa Electric: Supplies process analytical instruments including free and total chlorine analyzers for water utilities and industrial plants as part of a much larger industrial-automation portfolio.
