Endress + Hauser launches Memosens CCS51D amperometric sensor for the measurement of free chlorine
Routine disinfection is an essential step in water treatment and legally required in many areas to protect people and systems from disease or damage. However, large doses of disinfectants such as free chlorine and chlorine dioxide can be toxic, which means that compliance with the limit values for these disinfectants is also very important. The CCS51D amperometric free chlorine sensor from Memosens enables safe and efficient disinfection by providing stable and fast measured values.
Savings on disinfection chemicals
Free chlorine is the most widely used disinfectant in water treatment due to its easy handling, strong disinfecting effect and low residual effects. Precise control of the dosage of free chlorine can only be achieved by rapid and sensitive measurement of free chlorine. The Memosens CCS51D amperometric chlorine sensor has a special membrane that provides an extremely fast response time. It helps operators to manage their disinfection processes within strict limits and to save on chemicals.
Long-term security and stability
The convex membrane of the sensor made of dense, dirt-repellent material prevents fouling and makes it extremely resistant to bio-fouling. Ultrasonic welding of the membrane to the sensor cap ensures its integrity, thus avoiding dilution of the electrolyte and therefore a drift of the measurement signal. This guarantees long-term stable measurements, the assurance of efficient and trouble-free disinfection.
Increase process uptime
The amperometric free chlorine sensor is equipped with the proven Memosens technology . Memosens enables direct commissioning of new sensors without additional calibration. During operation, the operators of the installation can pre-calibrate the sensors in the laboratory, invert them in the process simply in Plug & Play, and thus continue to measure more quickly. Finally, the contactless data transmission eliminates all measurement errors or even failures due to humidity or corrosion.
Easy integration of pH measurement
The disinfection efficiency of free chlorine strongly depends on the pH value. To compensate for this dependence, it is important to integrate a pH measurement in all free chlorine disinfection processes. The Memosens CCS51D amperometric chlorine sensor is connected to the Liquiline multi-parameter transmitter which can power up to 8 sensors simultaneously, and theFlowfit CCA250 set offers mounting space for simple installation of the additional pH sensor.
