Hamilton's highest conductivity liquid standard is a 100,000 μS/cm value with a certified accuracy of ±1% and a lifetime of 3 years. 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.
