Hanna Replacement Reagents

These high-quality reagents are pre-measured, allowing for users to achieve fast and accurate measurements with each of their pocket checkers. These reagents follow the DPD Method in which the reaction between the element and reagent causes a tint in the sample. By simply adding the packet of reagent to the sample, the reaction will take place and you can determine the concentration from the colour that is produced. The results will be displayed on the pocket checker LCD screen.
