Hanna Instruments Water Analysis Division has released the HI 38058 pH chemical test kit.
The pH value of water is related to a large number of dissolved substances and is therefore a good indicator of the quality of water. In applications where water is treated chemically, the pH value should be measured continuously. In chemical reactions, the solids present in wastewater precipitate and the water is neutralised and decontaminated. During these reactions, the pH must be kept at the right value, since a solution that is too acid or alkaline may interfere with the precipitation of solids and will influence the efficiency of the process. Hanna’s line of chemical test kits covers the pH range between 3 and 10. The colourimetric pH kits are also available with an additional reagent against chlorine interference.
