Monitoring your needs

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.

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 oft, damp cloth. Do not use abrasive

materials.

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.
