Our sensors provide high-precision control for drinking water and swimming pool applications, striking a perfect balance between effective disinfection and regulatory compliance to ensure superior water safety.
These sensors are also designed for the harsh environments of industrial cooling water, offering stable measurements and long-term reliability. They feature automatic brush heads to prevent biofilm buildup and protect infrastructure from corrosion.
The ADS2 controller is specifically designed for membrane-covered ampere systems, providing high-resolution data visualization and precise calibration, and is compatible with a variety of disinfectants.
Equipped with programmable setpoints and relay logic, the ADS2 supports customizable automatic dosing and alert functions, maintaining precise chlorine concentrations without manual intervention. Save on your budget while ensuring compliance with environmental regulations and safety requirements.
The municipal water treatment plant in Malaysia struggled with inconsistent free chlorine residuals due to fluctuating source water quality, leading to increased operational costs and strict regulatory compliance pressures.
Integrated the ADS2 Smart Controller with CL-series membrane-covered sensors to provide automated, real-time feedback control for the chemical dosing system.
Achieved consistent 24/7 water quality compliance while reducing chemical waste and manual oversight through precise automated dosing.
Industrial cooling water systems in Saudi Arabia face rapid depletion of free chlorine due to extreme desert heat, leading to severe biofouling that degrades heat exchanger efficiency and threatens continuous plant operations.
Deploying ADS2 disinfectant controllers with membrane-covered amperometric sensors enables precise, automated oxidant dosing to maintain optimal residual chlorine levels despite extreme ambient temperatures.
Precise disinfection control reduced biocide consumption by 20% while maintaining consistent heat-transfer efficiency across all cooling towers. Reliable monitoring prevents 100% of biofouling-related shutdowns, ensuring uninterrupted power generation and significantly extending the service life of critical infrastructure.
Water treatment facilities in the United States struggle with unpredictable chlorine decay across extensive, aging distribution networks, resulting in chemical overdosing at treatment plants while failing to maintain mandatory residual levels at distant customer taps.
Deploying ADS2 disinfectant controllers equipped with CL4.2 membrane-covered amperometric chlorine sensors enables automatic, real-time dosing control across long-distance networks to stabilize residual levels.
Continuous residual chlorine tracking has reduced chemical overdosing by 18% while guaranteeing safe, compliant drinking water at all peripheral network nodes. Eliminating manual grab sampling saved the utility over 200 man-hours monthly and ensured 100% adherence to EPA secondary disinfection regulations.
Utilizing the advanced membrane-covered amperometric principle, the sensor measures free chlorine by detecting the electric current generated from the electrochemical reduction of hypochlorous acid (HOCl) at the cathode.
The specialized selective membrane allows only chlorine molecules to permeate while blocking ionic interference, ensuring high sensitivity and a stable zero-point for precise low-level detection.
This reagent-free measurement method provides continuous real-time data with integrated temperature compensation, significantly reducing operational maintenance compared to traditional DPD colorimetric methods.
Precise residual chlorine control is essential to prevent the formation of harmful disinfection byproducts (DBPs) that threaten aquatic ecosystems and long-term environmental health. By optimizing chlorine levels, you protect local biodiversity and ensure your water discharge meets the strictest environmental sustainability standards for a greener future.
