Explanation
In this example,
• the water filling the tank has a permeate
conductivity of 6 µS/cm.
• the water dispensed from the POD Unit has:
− a resistivity of 18.2 MΩ.cm,
− is temperature compensated (TC) at 25°C, and
−
the TOC value is 4 ppb.
In this example, there are no Milli-Q® water quality
measurements to display. The water quality is only
displayed when it is actually measured during water
delivery or recirculation.
