Field of application
Memosens CCS51D is a robust, low-maintenance sensor for free chlorine. It provides high-precision measurement with long-term stability in drinking water, pool and process water and ensures consistent disinfection monitoring even at low water volumes. The free chlorine sensor features extremely fast response times guaranteeing efficient process control. Memosens CCS51D is not the latest Memosens generation. More information on the new Memosens CCS51E sensor with extended functionality here.
Memosens CCS51D is a free chlorine sensor for skid builders and end customers. It measures reliably in:Drinking water – to ensure reliable disinfectionProcess water – for hygienic and safe packaging and bottling of productsUtilities – to detect the absence or presence of free chlorinePool water – to dose disinfectant efficiently
Benefits
The right sensor version for every application: From trace measurement up to free chlorine concentrations of 200 mg/l. Fast response time (t90 < 25 s) provides an accurate process view and enables prompt reaction to process changes as well as efficient process control.Increased process safety: precise and long-term stable measurement ensures consistent process monitoring and allows for individually adapted disinfectant dosing. The low-maintenance, amperometric sensor reduces the cost of ownership of the measuring point, particularly compared to colorimetric measuring systems. More process up-time thanks to fast sensor exchange: pre-calibrate the sensor in your lab and then swap it into your process with plug & play.Connection to the Liquiline multiparameter transmitter allows for easy combination with other relevant parameters of liquid analysis such as pH and ORP.
