Measurement System for Free Chlorine

June 12, 2012

KROHNE, Inc. introduces the OPTISYS CL 1100, a device for determining the chlorine content in drinking water for measuring free chlorine in the emergency chlorination of waterworks. This measurement system is ideal for disinfection of clean water, monitoring of chlorine as a growth inhibitor and product disinfection. In the OPTISYS CL 1100, 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. The sensor features two gold electrodes on the outside, which are also resistant to fouling, making the OPTISYS always ready for use, even if no chlorine has been added for a long period of time.
