1.4 Features of the VisoTurb
®
700 IQ (SW)
Turbidity measurement
according to
EN ISO 7027
The turbidity measurement in aqueous media with the VisoTurb
®
700 IQ (SW) is conducted nephelometrically in accordance with EN
ISO 7027.
Total suspended solids
measurement
The turbidity/total suspended solids sensor can also be used to
determine the total suspended solids content in the sample. The
appropriate correlation for the given application can be determined via
a reference measurement. After this adjustment, the turbidity value is
converted into the concentration of total suspended solids.
Ultrasound cleaning
system
The ultrasound cleaning system ensures low maintenance and long-
term reliable measurement operation.
The ultrasound source integrated in the sensor excites the sapphire
disc at the tip to produce vibrations in the ultrasound range. The
movement of the surface as a result of this prevents the growth of
pollution in almost all cases and, thus, ensures reliable measured
values during continuous operation.
AutoRange function The AutoRange function selects the optimum resolution for the
respective measured value from the enormously large measuring
range (0 - 4000 FNU).
SensCheck function This monitoring function that is integrated in the sensor is used to
continually check the sensor function and to register any malfunctions
caused by the measuring medium. The correct operation of the
ultrasound cleaning system is also continuously monitored.
