FC^E: Groundbreaking Measurement of Free Chlorine Disinfecting Power in a Handheld Instrument

Company Reference: 

The Myron L Company Free Chlorine Equivalent (FCE) feature directly measures ORP, the germ-killing property of chlorine and other oxidizing germicides. It displays both the ORP reading (in millivolts DC) for the sample being tested as well as an equivalent free chlorine concentration in familiar ppm (parts per million). It accounts for the very significant effect of changing pH on chlorine sanitizing power; can be used for other types of oxidizing germicides and; will track the effect of additives, such as cyanuric acid, that degrade chlorine effectivity without changing the actual concentration of free available chlorine present.
