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...
