Temperature Influence of Conductivity Standard 15 µS/cm

Hamilton offers the 15 µS/cm liquid conductivity standard (Ref 238927), 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. The product uses a glass bottle to avoid any further contamination due to permeation from outside air. 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.
