The Model CP3230-OCl sensor is intended for measurement of free residual chlorine (hypochlorous acid plus hypochlorite ion) in water.
l 饮水厂Measuring chlorine levels in drinking water.
l 加氯工艺Chlorine Adding control.
l 次氯酸钠发生器Hypo chlorite measurement in electrolysis generator
l 脱氯工艺Monitoring dechlorination processes.
The sensor requires no acid pretreatment and
can measure free chlorine in samples having pH as high as 9.5. The minimum
linear range of the sensor is 0 to 10 ppm about.
The CP3230-Cl2 is a membrane-covered amperometric sensor. The sensor consists of a proprietary porous membrane stretched tightly over a platinum cathode. A silver anode and an electrolyte solution complete the internal circuit. During operation, free chlorine (hypochlorous acid plus hypochlorite ion) diffuses from the sample through the membrane. A polarizing voltage applied to the cathode completely reduces free chlorine to chloride ion. The reduction produces a current between the cathode and the anode, which the analyzer measures. The current is directly proportional to the rate at which free chlorine diffuses through the membrane, which is ultimately proportional to the concentration of free chlorine in the sample.
Instrument to measure sodium hypochlorite:
TBD5-CPT3230-OCL transducer is designed for on-line application;
H-BD5w-Ocl is portable for laboratory or at field smart analysis.
