The turbidity of a test sample is part of the
sample matrix and affects the measured
value of online measurements.
The effect of the turbidity on the measured
value is eliminated in the laboratory by mea-
suring a filtrated sample.
The effect of the turbidity measured in the lab
can be entered in the sensor as the
Factor
turbidity to achieve a permanent turbidity
compensation.
