Krohne has introduced the OPTISYS CL 1100, a device for determining the chlorine content in drinking water and for measuring free chlorine in the emergency chlorination of waterworks. Chlorine is measured by a sensor with a three-electrode design, which uses a patented automatic sensor cleaning, to ensure long life span and extremely low maintenance. It also features a membrane-free potentiostatic sensor, with no pores that can be clogged by biological fouling.
