These conductivity standards are aqueous and so avoid the problems of matrix errors and high temperature dependency of nonaqueous conductivity standards.

• With an accuracy of ±1,0% (except 1,3 µS)
• Temperature dependence data, lot no. and expiry date are printed on product labels

These solutions standardised at 25 °C are directly traceable to N.I.S.T standard reference materials and are tested using an ISO 17025 accredited method.
