Regular use of the conductivity standards in factories and laboratories guarantee instruments are properly calibrated at all times for accurate readings. Placing probes into the solution with an identified transfer ability, the equipment settings can be adjusted prior to testing. The equipment maintenance permits estimations of impurities and ion levels present in samples. Meeting industry regulations, the solutions are created under strictly controlled conditions for complete working stability and reliability.

Conductivity standards, KCl, referenced at 25 °C

Supplier: REAGECON

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

A slight change in temperature usually has a big impact on the conductivity value of a standard solution. A table on every bottle label indicates the conductivity values at the most common measurement temperatures.
During calibration the meter automatically references to this table for temperature compensation. If possible, calibration and measurements should be performed at the same temperature
