CARE AND MAINTENANCE
The Compact Turbimeter has been tested for IP67
compliance so accidental immersion will not damage
the internal components.
Sample cuvette should be clean and dry prior to
insertion into the sample holder. Lint free cloths are
provided for this purpose.
Silicon oil is also present to use on scratched cuvette
surfaces. Its use should not be necessary unless
turbidity readings are consistently higher than expected.
If required place two or three drops onto the vial and
smear across the glass using the lint free cloth.
Indexing cells to find the optimal position for turbidity
measurement is recommended, especially if measuring
low values. The Continuous-Capture reading mode (see
Page 14) contains more details on the suggested
method.
User calibration is advised on a need-only basis, using
the supplied SDVB standards. Calibration frequency is
at the user discretion and can be deduced by reading
the standards to determine any offset that may have
occurred due to fouling.
Subjecting the standards to prolonged exposure to
freezing temperatures will destroy the SDVB standards,
seen by physical settling and a lowering of the NTU
value. The use of a WP48 Heat Pad is recommended in
these circumstances to prevent standard degradation.
