4.2.4 Measuring turbidity using the flow-through
vessel (accessory)
The flow-through vessel (WTW order number 600605) fits to
each Turb 555 /Turb 555 IR instrument and enables you to
continuously measure a sample flowing through and to no-
tice turbidity changes immediately. Using the periodical
measured value output, you can output the current mea-
sured values periodically to a printer or PC connected.

Note
Measuring with the flow-through vessel makes it necessary
to purge the cuvette shaft with dry air or nitrogen. Otherwise,
the outside of the cuvette may mist up after pouring in due
to a cold sample, causing the measured value to be much
too high.
Maximum pressure: 4 bar (60 psi)
Recommended flow-
through quantity: 2-5.5 l/min (0.5-1.5 gpm)
