AMPEROMETRIC CHLORINE ANALYZER EVOLUTION Early on, the electrochemical approach to chlorine measurement earned a reputation for being less accurate than colorimetric. . The cell consists of a casing containing a gel or electrolyte and two active electrodes: the working electrode (anode) and the counter-electrode (cathode). To kill bacteria completely in a certain period of time, combined available chlorine is required about 25 times more than free available chlorine in terms of quantity. Looking for more information on our people, technology and solutions? By measuring the hydrogen-ion activity in water-based solutions, this sensor gets a pH reading. The fundamental working principles, as well as the sensing mechanisms of chlorine detection covering spectrophotometric, electrochemical, and optical techniques, are described. A photocell or photoresistor is a sensor that changes its resistance when light shines on it. Sometimes free available chlorine is also called free chlorine, and residual chlorine is also called total chlorine. Why? This holds true across a wide range of measurement values: field tests have shown similar results for optical and galvanic DO sensors from ~1mg/L up to 14mg/L. 0000000016 00000 n
