Online Chlorine Dioxide Analyzer with CD10.1 Sensor for Processing Water
Published on by Susan Su for Dabeco
The online chlorine dioxide analyzer is equipped with a German-made CD10.1 sensor, adopting special osmotic membrane technology. It resists chemical interference (mainly surfactants), reduces pH dependence, and is not restricted by water quality. With fast response, stable performance, low cost, minimal maintenance, it delivers reliable and accurate data.
Its application fields include tap water, chlorine dioxide generator, sewage treatment, pipeline disinfection and fruit and vegetable disinfection etc.
Functional Features
Dual-channel access, allowing for configuration according to specific needs.
Plug - and - play sensors are realized, enabling fast and convenient installation and replacement of electrodes.
The operation interface is simple, reducing operational errors and ensuring reliable results.
Visual operation on the LCD screen, with a rich and comprehensive interface content.
It has multiple data output methods, such as 4 - 20mA and MODBUS RS485.
The controller supports wall-mounted installation, panel installation, and clamp-tube installation.
Made of aluminum alloy material, it has high strength, oxidation resistance, and corrosion resistance, enhancing its texture and market attractiveness.
Working Principle
The entire measurement system mainly comprises two components: the instrument and the sensor. The instrument displays the chlorine dioxide value (the main measured value), the pH value of the aqueous solution (a pH electrode is optional), and the working status. It outputs signals such as analog quantity, digital quantity, and switching quantity.
The sensor adopts the original imported RG brand from Germany and operates on the principle of the constant current method of the three (double) - electrode film - covered type, which has the characteristics of anti - interference and anti - pollution. The sensor is not restricted by water quality conditions and can be applied in various industries.
