Spectral Attenuation Coefficient
(254)
analogous to DIN 38404
Shake the unfiltered
sample solution to
e
venly suspend the
turbidity-causing sub-
stances
. Do not disperse
the contents, measure
immediately.

Note:
When the turbidity correction function is activated (see Descrip-
tion of Function, section 4.5.9 “Automatic Turbidity correction”),
the corrected spectral attenuation coefficient (254)korr can
be determined.
The turbidity correction is carried out as per DIN 38404 at
550 nm.
