Understanding conductivity values
6.4.2.1
General information
The global quantity of dissolved solids in water can be measured by the CONDUCTIVITY (expressed in
microSiemens per centimeter (µS / cm).
6.4.2.2
Production conductivity « output of water purifier »
Class 2 water (see ISO 3696 standard)
Convenient for clinical analyzers.
The conductivity of the
produced water is below
1µS/cm
The conductivity indicator
is switched OFF
Class 3 water (see ISO 3696 standard)
If the desired water class is 2:
1.
Replace the resin (see paragraph
2.
Follow the instructions of paragraph
HI
(too high) is displayed
when the conductivity is
between 1.1 µS/cm to
5µS/cm
The conductivity indicator
is ON with yellow colour
1.
Replace the resin (see paragraph
2.
Follow the instructions of paragraph
SAT
(saturated) is
displayed when the
conductivity is above

The conductivity indicator
is ON with red colour
When the conductivity is
above 9.9,
