Conductivity
For conductivity, the values in the following table are valid, if the cell constant k is set to the
nominal value according to column 2.
Otherwise: Display conductivity [mS/cm] = k[cm

measurement is normally used for pure and ultrapure water and therefore is
only wise for cell constants where k= 0.01 or k = 0.1 cm
