Conductivity standards
Standard solutions for calibrating conductivity meters and for determining the values of total dissolved solids (TDS meters). If you require accurate and reproducible results from your conductometer, then calibration using pre-prepared standard solutions is necessary. Potassium Chloride (KCl) is the most popular calibration solution because it is soluble and stable. The composition of the conductivity standard solutions is the KCl: Water ratio. Always use fresh solution and carry out the procedure in a plastic container, as the use of metal containers may affect calibration. Available solutions for calibrating conductivity and TDS meters are ready to use. Hach Lange offers certified NaCl and KCl standard solutions in various concentrations. Below are the most popular calibration solutions for conductivity and TDS meters:
