Online Chlorine Dioxide Analyzer with CD4.2 Sensor for Municipal Tap Water
Published on by Susan Su for Dabeco
An online analytical instrument that adopts a genuine German-imported CD4.2 sensor and operates on the principle of the coated dual-electrode constant current method; it is widely applied in municipal tap water treatment, secondary pressure-boosted water supply systems in pipe networks, as well as water quality monitoring for food factories and beverage factories, and boasts a suite of outstanding features including a fast response speed of up to 15 seconds , built-in automatic temperature compensation to enhance measurement accuracy, no requirement for zero calibration, a flexible measurement range, two input signal interfaces supporting simultaneous measurement of one additional parameter such as pH, ORP, conductivity, turbidity, or dissolved oxygen, multiple data output methods, support for diverse controller installation modes and a durable structure made of cast aluminum with high strength, oxidation resistance, corrosion resistance, and an IP65 protection class.
