Temperature Influence of Conductivity Standard 5

Hamilton is the first manufacturer to offer conductivity standards at 5 μS/cm, with a certified accuracy of ±1% and a 3-year lifetime. To prevent any gas permeation from the atmosphere, which could affect conductivity, this product is specially packaged in a 250mL 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 (DFM) and the National Institute of Standards and Technology (NIST). Please refer to the calibration certificate packaged with every HAMILTON Conductivity Standard for further details.
