Absorbance measurement
Fig. 10: Enter wavelengths
An absorbance measurement can be
performed within the wavelength range of
340–800 nm for up to 20 different wave‑
lengths simultaneously. By selecting
Basic
functions > Absorbance
, the desired wave‑
lengths can be entered via
λ
Confirm the entry with clicking on "Enter". The
entered value is accepted in the list. Press
to start the measurement process.
Insert the cuvette with the zero solution and
press
. Insert the sample cuvette and

NTU-Check
Fig. 11: NTU‑Check
The
NANOCOLOR
®
Advance provides
a warning of interfering turbidity when
measuring a test in the 16 mm and 24 mm
test tube.
The NTU‑Check is activated ex works.
Parallel to the measurement, the nephelo‑
metric turbidity is determined by measuring
at 860 nm at a 90° angle. The NTU value
is displayed together with the result (Fig.
11). If the preset warning limit of 10 NTU is
exceeded, a warning is issued and the result
is displayed in red. The measured turbidity
value is stored together with the result.
