Hamilton offers the 12880 µS/cm liquid conductivity standard (Ref 238988), whose stability of ±1% is guaranteed over a lifecycle of up to 3 years. These standards can be used several times, on condition that the bottle is not left open without its lid for more than one hour total. The composition of these standards is patented, and the procedure for determining conductivity has been developed in collaboration with the Danish Institute of Fundamental Metrology (FDM) and the National Institute of Standards and Technology (NIST). Please refer to the calibration certificate packaged with every HAMILTON Conductivity Standard for further details.
