Cell for selective analysis of oxidising substances, low sample consumption, Mod.605

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.
Max. salt concentration in the sample: 100 g/l  of chlorides (Cl^-)
Max. limit for sample hardness is 10°f; above this limit  frequent cell clenaing may be required.
We highly recommend the installation of a filter able to prevent suspended particles with a diameter higher than 0,7 – 0,8 mm from entering the measuring cell.

Some of the typical use of these selective cells:  measure and control of chlorine, chlorine dioxide, chlorites, ozone, peracetic acid, hydrogen peroxide, bromine for the following applications:
dosage of disinfectant  in drinking water,
control of disinfection in the in IV range products preparation
determination of chlorine or other oxidizing substance  in sea water
analysis of the oxidizing agent (e.g. peracetic acid, chlorine dioxide, chlorine etc.) in fruit and vegetables disinfection and processing
measure of chlorine in swimming pool water
disinfection of bottles in bottling machines
