4.2.3 Measuring turbidity using the pour-through
vessel (accessory)
The pour-through vessel (WTW order number 600600) fits
any Turb 555 /Turb 555 IR instrument and enables you to
measure several samples one after the other quickly and
easily. Any interference effects caused by air bubbles are
reduced. Besides, you do not have to use balanced cuvettes
for comparative measurements as always the same cuvette
is used.
Note
If you measure cold samples, the outside of the cuvette may
mist up after the sample is poured in causing the measured
value to be much too high. Therefore, we recommed to
purge the cuvette shaft with dry air or nitrogen (see section
4.2.4). Otherwise, you have to wait until the sample has
reached room temperature before filling.
