Hamilton is the first manufacturer to offer conductivity standards in 5 μS/cm with a certified accuracy of ±1% and a lifetime of 3 years. To avoid any permeation of gases from the atmosphere which could influence conductivity, this product comes specially packaged in a 300mL glass bottle.

The composition of the 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.
