4.10 Turbidity measurement (VisoTurb
®
900-P)
4.10.1 General information
Measured parameters You can measure the following parameters:
 FNU
 NTU
Note
The sensor connection and the USB-B (device) interface are galvani-
cally isolated. This facilitates interference-free measurements also in
grounded measuring media.
The sensor connection and the USB-B (device) interface are galvani-
cally isolated. This facilitates interference-free measurements also in
the following cases:
 Measurement in grounded test samples
 Measurement with several sensors connected to one Multi 3410 in
one test sample
Preparatory activities  Avoid gas bubbles (e.g. air bubbles) in the test sample.
 Use suitable vessels for measurement and calibration
(see operating manual of the VisoTurb
®
900-P sensor).
 Heed the minimum depth of immersion for the sensor
Perform the following preparatory activities when you want to measure:
1 Connect a turbidity sensor to the measuring instrument.
The turbidity measuring screen is displayed.
The data for the connected IDS turbidity sensor are automati-
cally taken over.
2 Fill the test sample into a lightproof measuring vessel up to a
level of at least 8 cm.
3 When immersing the sensor in the test sample, hold the sensor
at an angle.
4 For measuring, position the sensor upright.
5 Position the sensor in a way that meets the following require-
ments.
 Distance to the bottom: 6 cm
 Distance to the walls of the vessel: 2 cm
 Minimum depth of immersion: 2 cm
