Type I Ultrapure water (UPW) is water that has been purified to remove all contaminants, containing by definition only H20, and H+ and OH- ion in equilibrium. Therefore, ultrapure water conductivity is about 0,055 uS/cm ( also expressed as Resistivity of 18.2 MegOhm.cm ) at 25oC.
Ultra pure water is water nearly or completely devoid of contaminants.
