Disinfection: Chlorine CCS140

The sensors for free chlorine CCS140 is an amperometric, membrane-covered sensor for installation in the CCA250 assembly. Oxidising agents such as chlorine or anorganic chlorine compounds are used for disinfection of water. Their dosing must be carefully controlled to suit the application. Too low a concentration makes the degree of disinfection questionable. Too high a concentration can result in corrosion effects, impairment of taste or skin irritation. Benefits: Minimum flow rate for installation in the CCA250 flow assembly: 30 l/h Measurement almost independent of flow rate in the range above 30 l/h No zero point calibration necessary. This means complicated installation of an active carbon filter, as in open chlorine sensors, is not necessary. Measured values are not affected by conductivity fluctuation. The CCS140 sensor is ready for measurement after a polarisation time of approx. 30 ... 60 minutes. The CCS141 sensor requires 45 ... 90 min. Easy membrane replacement thanks to ready-made membrane head Recalibration intervals approx. 1 ... 4 months under constant operating conditions Back pressure up to 1 bar / 14.5 psi allowed at the outlet
