Is it possible to use a CL17 to measure Chlorine Dioxide?
Using the CL17 total chlorine analyser to measure Chlorine Dioxide.
It is possible to use the CL17 to read chlorine Dioxide. However, there are a few things to take into consideration:
The ratio of the molecular weights are similar. That value would be 99.45 (MW of ClO 2 )/70.9 (MW of Cl 2 ) = 1.4. So a 1.0 ppm Cl 2 reading on the display would be equivalent to 1.4 ppm ClO 2 (1.0 x 1.4 = 1.4) This conversion/adjustment would need to be performed by the end user or operator of the CL17 as there is no option in the analyser to automatically compensate for the difference.
