Founded in 2013, Halogen Systems, Inc. specializes in using chlorine analyzers to solve challenging problems in water monitoring. Proven in the tough environment of Ballast Water Management Systems for ocean-going shipping vessels, Halogen’s patented technology uses no membranes or reagents and is impervious to flow, pressure, and turbidity changes. Our amperometric chlorine analyzers are well suited for nearly any water testing need, from Ballast Water to Drinking Water, and can be used in a wide variety of installation types, from direct-pipe insertions to side-stream testing boards or even submerged in tanks. 

Water conservation is paramount in being good stewards of our environment, and municipal water facilities constantly seek ways to conserve water. One effective measure is eliminating waste streams while capturing readings for chlorine levels. By installing Halogen Systems Inc.’s MP5, hundreds of water facilities save an impressive 70,000 gallons of water annually per sensor. This is the equivalent volume of three standard-sized swimming pools.  [Find Out More

Styles of Deployment Traditional Chemical Usage

By eliminating the need for reagents, tubing kits, and membranes, users stand to save an estimated $1000 annually per sensor. This financial efficiency not only reduces overhead but also underscores the economic advantages of our technology. The absence of these recurring costs contributes to a more sustainable and economically viable solution, making it a prudent choice for those seeking operational efficiency and financial responsibility.

Ballast Water Management Systems (BWMS) designers appreciate the reliability, accuracy, and flexibility they get from a system using Halogen’s TRO sensors. As with all Halogen sensors, the TRO needs no reagents or membranes and is unaffected by flow or pressure. In addition, Halogen TRO calibrations last for months. Truly, the TRO family is the perfect fit for the difficult operating environment of BWMS. [Find Out More]

Based on technology developed for testing Ballast Water Management Systems in Ocean-going Shipping Vessels, Halogen’s MP5™ is well suited for the difficult environments of Wastewater Treatment and Reclamation. With no membranes or reagents to replace and retaining calibration for months, the MP5™ is a simple choice for many engineers and plant operators who value long-term accuracy, durability, and reliability.
