Copper High Range Reagent HI702 RO/DI Filter Media or closed loop systemHanna HI702 includes 25 pre measured reagent packets that can be used with the HI702 High Range Copper Checker. Each package has been designed for a single use and allows for a perfect reagent measurement that will not become contaminated. The reagents use the Bicinchoninate Method which produces a purple tinted water when copper is present, allowing the HI702 Checker to produce a reading in parts per million.
