Thanks for you input
We already have pretty effiecient detectors to alert us to the presence of chlorine. We are now looking to quantify it. The detectors we have are designed for a lower level than the range we want to quantify, and are not able to be extended to the range we need for quantification and still remain dependable at the alarm level. I was hoping to find an instrument manufacturer that had an online instrument that would do the quantification while leaving our present monitors for the job they are doing now.
