TDS is a conductivity measurement and determines the ability a solution to conduct an electrical charge. TDS is commonly used to determine the concentration of salt in saltwater pools, hot tubs and spas. These bodies of water can use the process of electrolysis to convert the chloride portion of salt to chlorine. It is critical to maintain the ideal level of salt for the efficiency of the electrolytic process. Too little salt will result in too little chlorine being produced. Too much can make the pool unpleasant to swim in.

HI700384P Pool Line 6.44 ppt TDS Standard solutions is used for the calibration of TDS meters. HI700384P contains potassium chloride NIST 2202 SRM (Standard Reference Material) in deionized water for analytical use in accordance with ISO 3696/BS3978. Additional equipment used in preparation of the solutions including certified weight-checked balances, Class A glassware and certified thermometers.
