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

-3

-1

.

The specific resistance, , and the

specific conductivity  are

calculated from the following

equation:

 = R • 132,5 cm

or  [M • cm] =

R [M]

7,55 • 10

R [M]

with 1 = 1S

If the measurement result is

required for internal quality control

only, e.g. for entries in a check-

card, conversion is not necessary.
