The 84 uS/cm conductivity solution allows calibration of instruments with a conductivity scale of up to 200 uS/cm for the measurement of pure or distilled water.
It is a premium quality 84 µS/cm conductivity standard that is prepared against a NIST traceable potassium chloride solution. RXSOL conductivity solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution.
