When drinking water is disinfected through chlorination it is necessary to continuously control the actual free chlorine level. This is crucial in the first place to ensure efficient disinfection and secondly to prevent regrowth of microorganism in the finished water. For these two tasks it is necessary to carefully process control the level of free chlorine, also in order to prevent the concentration of harmful disinfection byproducts that can be formed in the presence of chlorine.  

Chlori::lyser™ monitors free chlorine mounted in a flow cell setup. Due to the membrane covered amperometric measuring principle, flow and pH fluctuations of the water do not influence the measurement result. Additionally, the integrated temperature compensation and the special, third electrode completely eliminates potential interferences.

Chlori::lyser™ monitors  free chlorine (CI2 + HOCI + OCI-) (optional: total chlorine or chlorine dioxide) 

• S::can plug & measure
• Measuring principle: amperometric (membrane covered)
• Ideal for drinking water
• Long term stable and lowest maintenance in operation
• Replacement of membrane only once a year
• Readings stable even at high fluctuations of pH, temperature and flow
• Compensates fluctuations of pH in an unmatched way (<5% per pH between 6 and 9 pH, <1% at <6 pH)
• Low cross sensitivity to many surfactants
• Cross sensitivities to chlorine dioxide, ozone can be compensated by using readings from spectro::lyser
• Factory precalibrated
• Mounting and measurement in a flow cell
• Operation via s::can terminals & s::can software
