Sensors for oxidizing substances (chlorine, chlorine dioxide, chlorites, ozone, peracetic acid, hydrogen peroxide, bromine, iodine, permanganate) in aqueous solutions, with high selectivity, sensitivity, accuracy and reliability. The sensor is made of a plexiglas chamber that houses the measuring electrode, the counterelectrode and the system for automatic sample flowrate adjustment. The electrodes are directly immersed into the sample that flows in the chamber with a constant flowrate, controlled by the cell itself; the electrodes are kept clean and active by the movement of the sample itself. The polarization voltage impressed across measuring electrode and counterelectrode makes the cell selective to different oxidizing substances. The cell is absolutely free of unwanted effects like corrosion of the electrodes: noises due to these phenomena are so forth completely avoided even in critical applications like sea water measurements. The cell is designed to be wall mounted through two screws diam.5 x 50mm; process connections are: 1/4” GAS F for sample inlet and 3/4' GAS F for sample drain. Measuring range: 0-2000 ppb, 0-10 ppm The special hydraulic design inside the cell assures high precision of the measure by keeping constant the flowrate of the sample inside the cell with no regard to the process sample flowrate that can vary inside the limits 15 to 200 l/h.
