Price on request
The S494CLO2 sensor is a three-electrode membrane-covered amperometric probe with internal electrolyte, which measures the presence of chlorine dioxide in water (equipped with built-in temperature sensor for signal compensation). The electrolytic solution is an aqueous solution containing potassium chloride, and the life time of the latter is approximately one year. The measuring electrode, the cathode, is gold, while the reference electrode, also called anode, it is silver or alternatively halogenated silver.
Furthermore, in order for the measurement to take place perfectly, the sample of liquid which is being considered must not contain surfactants.

Applications

• Pool water
• Drinking water
• Service waters
• Process water
