Compact Turbimeter
Readings are consistently higher
than expected.
Check the sample cuvette for dirt, scratches and
marks. Turbidity is an optical measurement and
will be adversely affected by unwanted items in
the optical paths.
Index the cuvette using the
‘Continuous-
Capture’
mode to ensure the most accurate
reading position is selected.
Apply a thin film of silicone oil to the cuvette to
‘fill in’ any scratches. Replace the cuvette with a
new, unused cuvette.
Check the calibration using the supplied standards
to ensure no offset has been inadvertently applied.
Recalibrate if necessary.
Readings are consistently lower
than expected.
Fouling in the optical chamber may prevent the
sources being transmitted with full intensity. The
unique
QuadoptiX™
system will prevent this issue
arising in all but the most challenging circumstances.
Gently clean the optical chamber using a soft,
damp cloth. Do not use abrasive materials.
Recalibrate the meter using the supplied
standards to remove the offset.
Readings are unstable/variable.
Turbidity is a measurement of scattered light with
the source of scattering being microscopic and
larger solids present in the sample. Solids can be
mobile or settle during measurement leading to
changes in readings over time.
Using the
‘Continuous-Capture’
mode will
show the changes over time.
Using the
‘Average’
mode will remove/reduce
the effects of settling or mobile solids.
The
QuadoptiX™
system measures at four
points and will also reduce the effects of solid
distribution across the sample cuvette.
Total Suspended Solids (TSS)
The relationship between TSS and turbidity is
a site/sample/season specific correlation and
will require frequent validation. If results vary
significantly from laboratory data a repeat
calibration should be carried out.
