  • NEW! FCE Free Available Chlorine (FAC) Function

    The Myron L Company FCE function reports FAC quickly and accurately by measuring ORP, the chemical characteristic of chlorine that directly reflects its effectivity, cross referenced with pH. Both DPD kits and colorimeters may tell the user the FAC value of the sample in the test tube, but since the chemistry of that sample is quite different from the source water being analyzed, the results are imprecisely related to actual disinfection power. The Myron L Company FCE function measures the real, unaltered chemistry of source water, including moment-to-moment changes in that chemistry.
