free chlorine measurement

free chlorine measurement


I'm struggling to find suppliers of instruments for on-line free chlorine measurement in water to ~300ppm

best I can find is ~20ppm from the likes of ABB, Yokogawa, and others

Before everyone says "that's helluva high", it is not for a water treatment application (is for makeup of chemicals for an industrial process) but as everywhere I look for chlorine measurement comes back to water treatment, I thought I'd ask here ;o)

Any ideas gratefully received....

RE: free chlorine measurement

They go to 200ppm with standard units and higher depending on the chemistry details of the application.
