4. Evaluation
The measured value constitutes
the resistance R [M] of the liquid
between the electrodes (in the
annular gap). The cell constant
which depends on the design and
dimensions of the measuring cell
is 7.55 10

.
The specific resistance,
, and the
specific conductivity are
calculated from the following
equation:
= R • 132,5 cm
or [M • cm] =
R

If the measurement result is
required for internal quality control
only, e.g. for entries in a check-
card, conversion is not necessary.
