Temperature Influence of Conductivity Standard 100 µS/cm (Ref 238934)

Hamilton offers 100 µS/cm liquid conductivity standard (Ref 238934) with a stability of ±1% 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. This standard is packaged in a glass bottle to avoid permeation from the atmosphere during storage. 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.
