Endress+Hauser launches Memosens CCS51D amperometric sensor for measuring free chlorine
Systematic disinfection is an essential step in water treatment and legally required in many areas to protect people and systems from disease or damage. However, high doses of disinfectants such as free chlorine and chlorine dioxide can be toxic, which means that compliance with limit values for these disinfectants is also very important. Memosens' CCS51D amperometric free chlorine sensor enables safe, effective disinfection by providing stable, fast measurement values.
Savings on disinfection chemicals
Free chlorine is the most widely used disinfectant in water treatment due to its ease of use, powerful disinfectant effect and low residual effects. Precise control of free chlorine dosage can only be achieved by fast, sensitive free chlorine measurement. The Memosens CCS51D amperometric chlorine sensor is equipped with a special membrane offering extremely fast response times. It helps operators to control their disinfection processes within strict limits and save on chemicals.
Safety and long-term stability
The sensor's convex membrane, made of dense, dirt-repellent material, prevents fouling and makes it extremely resistant to biofouling. Ultrasonic welding of the membrane to the sensor cap ensures its integrity, preventing dilution of the electrolyte and hence drift of the measurement signal. This guarantees stable, long-term measurements, as well as effective, trouble-free disinfection.
Increase process uptime
The amperometric free chlorine sensor is equipped with the proven Memosens technology. Memosens enables the direct commissioning of new sensors without additional calibration. During operation, plant operators can pre-calibrate sensors in the laboratory, then simply plug & play them into the process to continue measuring more quickly. Last but not least, non-contact 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 is highly dependent on the pH value. To compensate for this dependency, it is important to integrate pH measurement into all free chlorine disinfection processes. Visit Memosens CCS51D amperometric chlorine sensor is connected to the Liquiline multiparameter transmitter, which can power up to 8 sensors simultaneously, and theFlowfit CCA250 kit provides mounting space for easy installation of the additional pH sensor.
