Disinfection Sensors Amperometric Disinfection Sensors Walchem’s amperometric disinfection sensors offer a cost effective and reliable solution to your disinfection control requirements. Compatible with the WDIS and WebMaster® series controllers, the sensors continuously and directly measure the chemical concentration, without the use of reagents. We offer sensors, in varying ranges of concentration, for free chlorine/bromine, total chlorine, chlorine dioxide, ozone, peracetic acid and hydrogen peroxide. Whether the application is a cooling tower, food and beverage, drinking water, wastewater, or swimming pool, these sensors are the ideal solution. Summary of Key Benefits Low maintenance - no costly reagents or tubing to replace Broad range of applications - wide variety of oxidizers and measurement ranges Fast response - continuous measurement technique No waste - the sample can be returned to the process Free Chlorine/ Bromine Range (Nominal) Free Chlorine/Bromine - Extended pH Range Total Chlorine Chlorine Dioxide Peracetic Acid Hydrogen Peroxide Range (WDIS) Range (WIND) HOCl (100%) HOBr (100%) Ozone ClO2 (900%) NOT for use with isocyanuric acid or stabilized bromine HOCl (100%) HOBr (100%) Ozone ClO2 (100%) HOCl with isocyanuric acid NOT for use with stabilized bromine Flow rate of sample H2O2 (100%) Chlorine PAA Ozone (none may be present) 6.8 – 8.0 (pH must be stable within ± 0.10) Conductivity range of sample Response time Conditioning time
