Potassium chloride solutions referenced at 25 °C.

Supplier: REAGECON

A complete range of certified control standards with values ranging from 133 to 26,6 µS.

Supplier: REAGECON

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

Supplier: Cole-Parmer

Standard solutions are used for calibrating conductivity cells.

Supplier: HAMILTON BONADUZ

Conductivity standards with stability of ±1% - guaranteed over a lifetime of up to three years.

Supplier: LGC Standards PROMOCHEM

Conductivity standard, 147 µS/cm

Supplier: Mettler - Toledo

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
