C201 Colorimeter
C201 Colorimeter

Chlorine and chlorine-release compounds are frequently used as disinfectants in water treatment systems. Routine chlorination kills harmful micro-organisms and inhibits the build up of organic matter. The disinfection efficiency is a direct function of the level of free chlorine in a system. Total chlorine is the sum of combined and free chlorine.

It is essential that the right amount of chlorine is present - insufficient chlorine will decrease the disinfectant efficiency, while excess chlorine can cause process problems.

The C201 colorimeter measures free and total chlorine over the range of 0 mg/L to 6 mg/L.
