HSI’s amperometric analyzers have several unique advantages whether deployed in seawater as a TRO sensor, municipal drinking water chlorine analyzer, or wastewater chlorine sensor. The benefits of the Halogen Systems technology overcome many of the drawbacks of existing membrane amperometric and reagent feed systems commonly used.

High on the list of benefits are flow independence, self-cleaning electrodes, and lengthy calibration retention. These benefits are common to both the seawater-specific TRO series and the MP5 family. Both employ three-electrode amperometry using bare electrodes, an integrated cleaning system, and a built-in pH sensor. The integrated sensor package creates a durable, reliable, and cost-effective analyzer unlike anything else. See the list below, and click on the headers for additional information.

安培式传感器还可以测量高达20ppm的总余氯水平。传感器顶端的磁力耦合泵提供固定的恒定流量,穿过电极。所有安培式传感器都对流量敏感。产生一致的速度、灵敏度和信噪比,对于较低的TRO检测水平来说,效果更好。集成泵使用无刷直流电机。叶轮由工程聚合物配方制成,产生低摩擦和长寿命。

Halogen uses a bare 3 electrode sensor, eliminating the need to replace clogged membranes or replenish electrolyte required by conventional amperometric sensors. This results in much lower maintenance requirements. In competing amperometric sensors, diluted electrolyte requires periodic sensor recalibration. Halogen’s technology needs no electrolyte and this allows their analyzers to hold calibrations much longer. For more information, see the Amperometric Technology page.

The Halogen chlorine sensors have a patented cleaning feature called SensiCLĒNE™.  Polymeric beads held within the sensor cap abrade the electrodes to minimize biofouling and remove calcium carbonate that typically deposits on the electrodes during operation in seawater. The polymeric beads are motivated by the flow from the internal pump. For more information, see the SensiCLĒNE™ page.

HSI的氯气传感器不需要试剂或废物流,降低了维护和安装成本。比色系统,如Hach CL-17,需要每个月补充试剂,并定期更换泵和光学元件。这些都是很难解决的问题,而且管道会出现生物堵塞,需要更换。试剂和部件每年可能超过600美元,外加人工。

Most competitor amperometric sensors often still require membranes and electrolyte and so do not reduce maintenance or water waste. Unlike the MP5™, at time of writing no other amperometric chlorine sensor is approved for NSF-61 usage in drinking water without a required waste stream.

Halogen’s MP5™ is the only amperometric chlorine sensor approved for NSF-61 usage. it can be installed as a side-stream unit, directly in a pipe, or submerged in a tank with no required waste stream.  This makes the MP5™ a good foundational component for drinking water applications such as remote reservoir monitoring, or dead-end water aging analytics.

HSI’s sensor measures five different parameters every minute: TRO, Oxidation Reduction Potential-ORP, pH, Salinity, and Temperature. The sensor uses these measurements to compensate for changes detected in the water source. While the pH of seawater does not change much, in brackish or freshwater, the pH can change drastically. Even when used in freshwater, the sensor can use conductivity measurement to compensate for signal changes. In addition, the temperature sensor allows the sensor to make compensation for all the parameters over -2 ° to 35 °C. These readings enable the sensor to operate and deliver accurate readings in virtually any water condition that a ship may encounter.

Our sensor’s electrochemical stabilization technique is unique. We use this technique to prevent the passivation of the electrodes. Passivation due to organic poisoning is a frequent problem with bare electrode amperometric sensors. This approach enables our chlorine sensor to stabilize and provide accurate readings, usually within one to two minutes. In contrast, our competitor’s bare electrode sensors require up to 24 hours after starting up for reliable readings.

Our sensor measures water at velocities from zero to 4.5 meters per second with less than a 5% change in signal. It can accomddddplish this thanks to its integrated pump. HSI has the only total residual chlorine sensor capable of direct insertion into a pipe.

消除对废物流的需要,简化了安装和维护。如图2所示的热龙头版本,使我们能够从管道中取出传感器,而不需要排出管道。热水龙头安装方法免去了使用采样泵、开关阀、采样管和样品过滤。这种方法大大降低了安装成本。

Halogen uses a unique pH cartridge in its chlorine sensor system. The pH cartridge can withstand 10 bar to -0.7 bar pressures and rapidly wets if allowed to dry out, with its accuracy restored within 3 minutes. HSI is the only company with this type of pH electrode designed with these specifications in an amperometric chlorine analyzer. It does not require calibration for a year or affmore, and the cartridges last two years.

卤素系统公司对这项新技术的研究和开发已经获得了五项美国专利,两项韩国专利,一项中国专利,还有一些专利正在申请中。我们的氯气传感器克服了现有技术在测量几乎所有类型水中的总残留氧化剂(TRO)方面的许多限制。
