DescriptionConductivity standard solutions are used for calibrating a wide range of the conductivity instrumentation shown in this section EE. To calibrate your instrument, select a conductivity solution which is close to your measuring range and calibrate the instrument for optimal system accuracy. Standard Shelf Life is 1 year for all solutions except the CDSA-10 and CDSA-15 which have a six month shelf life. The conductivity solutions are recommended to be used within +/- 5% of 25 C. No temperature correlation charts are available for higher or lower temperatures. The conductivity solutions contain Potassium Chloride, a full MSDS sheet can be requested from our Customer Service department.
