Remote Chlorine Analyzer for 
Drinking Water Applications

The stable calibration and self-cleaning technology in the MP5™ chlorine sensor enable reliable low-maintenance remote tank and water grid monitoring.

Use the NSF-61 capable MP5 chlorine analyzer to monitor chlorine and other parameters at remote tanks, distribution trunks, or end-of-line areas in the water grid.

Because traditional chlorine sensors require frequent maintenance, analyzing chlorine residuals across a water grid or in remote tanks has long been a highly manual process, requiring truck roll-outs and grabbing samples.  

Unlike maintenance-intensive sensors, Halogen’s MP5™ Chlorine Sensor is self-cleaning and has been shown to maintain stable calibration for months in drinking water applications. In addition, the MP5™ is the only chlorine analyzer approved for NSF-61 use in drinking water tanks or pipes with no required waste stream.

Halogen has remote monitoring solutions that combine any MP5 with a battery and cellular-enabled remote telemetry. For remote tank operations, the MP5™ can be suspended in a tank, inserted in the fill pipe, or deployed at the outflow. In a similar fashion, MP5™ sensors can be deployed throughout a water grid without needing the electrical grid.

Operators can measure free chlorine, pH, temperature, conductivity, and ORP at nearly any point in the grid that has a cell signal. 

Remote Monitoring with the MP5™ Chlorine Analyzer

Halogen Systems, Inc - MP5 NSF-61 전류 측정 염소 센서 라인업


The NSF-61 certified, Halogen MP5™ measures 5 testing parameters in near-time using one online unit without losing a drop of treated water. Operators can assess free chlorine, pH, temperature, conductivity, and oxidation-reduction potential (ORP) in near-time in the pipe with no waste stream.


The MP5™ analyzer makes things simple. Our NSF-61 certification means no flow-control plumbing and no waste stream to mitigate. There are no reagents or membranes to stock, manage, or replace. Instead, you’ll replace the cap, cleaning beads, and impeller blade once per year in 5 minutes without affecting the calibration.

유량 및 압력에 영향을 받지 않는 할로겐 MP5 염소 센서 NSF-61


MP5™는 거의 모든 유량이나 압력에 적응할 수 있습니다. 건조한 파이프에서도 캘리브레이션이 손상되지 않습니다. 파이프에 직접 설치하거나, 사이드 스트림에 위치하거나, 트로프에 매달거나, 탱크에 떨어뜨릴 수 있습니다. 배포 유형이나 매개변수가 무엇이든 MP5™는 정확성, 신뢰성, 안정성 면에서 독보적입니다.

테스트를 현대화하는 특허 기술이 적용된 전류 측정 센서

Bare Electrode Sensor

Amperometric Sensors have many advantages over the older membrane and reagent technology.  Halogen’s implementation of bare 3-electrode amperometric technology provides pH-stabilized precise measurements of Free Chlorine without introducing additional complexity to your workflow.

Self Cleaning

The old amperometric technology used by competitor sensors still requires a membrane and electrolyte to guard against sensor fouling. Such membranes are sensitive to flow and pressure spikes. Halogen’s patented SensiCLĒNE™ technology prevents fouling without introducing pressure or flow sensitivity.
