Measuring high levels of free chlorine can be problematic; Colorimeters used to test free chlorine are based on a colour change test; The DPD 1 (N,N-diethyl-p-phenylenediamine) method for residual chlorine was first introduced by Palin in 1957. Over the years it has become the most widely used method for determining free chlorine in water and wastewater. Hach introduced its first Chlorine te...
Higher range chlorine solutions are typically used for disinfecting products but standard chlorine meters often cannot measure to higher ranges. For example the Hach Pocket Colorimeter II for chlorine measures to a maximum of 2mg/L, and the MD100 Duo for Chlorine measures to a maximum of 8mg/L There are several instruments available for samples where chlorine levels are high, lets take a ...
