Product Description Product Description Water Hardness Test Strips TO MAKE IT EASIER AND FASTER PrincipleBased ob EDTA complexometric titration.The EDTA complexometric titration method is a commonly used chemical analysis method for determining the hardness of water. It is under certain conditions, with chrome black T as indicator, NH3 ·H2 O-NH4 Cl is a buffer solution, and EDTA forms a stable complex with calcium and magnesium ions ,to determine the total amount of calcium and magnesium in water. Specification Range:0-5-10-15-20-25 d 100 pcs / box Application It can be applied to the rapid detection of water hardness in food processing, medical and health industries, and also as a supporting tool for water treatment equipment. Feature1.Quick and easyAccording to the instructions, users can complete the nickel analysis independently without specialized training.2.Accurate and reliable Determination results with this method are in accordance with the results with the standard method. It can be used as an alternative method to the standard method.3.Quantitative packingThe kit can be used for100 times. It is small, light and easy to carry. UsagePackaging & Shipping Packing : 100 Tests / Box Unique aluminum tube packing for inner packing ,plating antioxidation film and outer packing with tray box . Company Information Our Services1.Offering Sample for Testing .2.R & D team to provide technical support.3.Provide packaging, labeling OEM customization FAQ Q1: I purchased DPD reagent with gray spots, is it normal?A: DPD residual chlorine, total chlorine, ozone reagent kits supporting the reagents are tablets. Due to the differences in the color of the DPD material, the color of the product may be white, light gray or pale pink. If the tablet is dark, sticky, do no use it . Q2:How often should the measurement be completed?A: Because DPD residual chlorine, total chlorine, ozone reagents react with the oxidizing substances in the air, resulting in color deepening. Therefore, we suggest to finish the testing within 5 minutes after the addition of the reagent.Q3:What are the factors in the water that interfere with the measurement?? Oxidizing agents: bromine, iodine, bromamine, iodine, ozone, hydrogen peroxide, chromate, manganese oxide.? Reducing agent: nitrite etc..
