Conductivity Measurement in High Purity Water Samples Below 10 microsiems/cm

2021-12-07T07:22:42-05:00February 1st, 2012|

Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H+ and OH- ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 μSiemens/cm or a resistivity of 18.18 mΩ·cm at 25°C. In order to know the conductivity or resistivity of ultra-pure water [...]
