Conductivity readings are only as reliable as the standard behind them. Thermal Scientific carries conductivity standards from Ricca Chemical, Traceable, and LabChem, from low-range potassium chloride standards to high-range sodium chloride solutions, so you can calibrate close to the range you actually measure. Matching the standard to your samples, whether treated water or high-salinity brines, keeps readings accurate where it counts.
Pair your standards with the right instrument: browse our conductivity meters and portable pH and conductivity meters, and see related pH buffers and total dissolved solids standards.
Choose a standard close to the conductivity of the samples you measure, and follow your meter manual for the calibration values it recommends. If you need a specific value, such as 12.88 mS/cm, contact our team and we will help you find it.
Potassium chloride (KCl) and sodium chloride (NaCl) solutions are the most common, available at defined values from low microsiemens to high millisiemens ranges.
Many TDS meters are calibrated against a conductivity standard, so check your meter manual. See our TDS standards page for more.
