TurbiLab - Model FS -Turbidimeter
The laboratory turbidimeter model TurbiLab-FS uses the principles of 12° forward- and 90° side scattered light, to detect suspended particles in liquids. The instrument detects the turbidity of the liquid only, product- or bottle colour will not affect the measuring results The measurement will be done directly in a bottle or in a cuvette. The bottle respectively cuvette, turns around its own axis during the measurement cycle. The water inside of the measurement chamber equalizes scratches and unevennesses of the bottles. The measurement result is calculated from average of 200 measurements per bottle rotation.
A ratio measurement of direct- / scatter light assure additionally for highly reliable and repeatable measurement results Comparing 12° and 90° measurement results will allow conclusion of particle size distribution inside the measured liquid The device is factory pre- calibrated by using a Formazin suspension (internationally accepted turbidity standard). The typical calibration interval is 12 month. The measurement values will be displayed in EBC units, alternative in FTU, NTU or ppm (units can be switched by using the keypad).
The instrument used as a stand-alone unit and operated from its keyboard, allows:
Application examples:
- Turbidity of water
- Turbidity of wort
- Turbidity of unfiltrated beer
- Turbidity of filtrated beer
- Forcier Test
Model TurbiLab-FS with optional software package allows:
Application examples (kinetics):
- Monitoring & logging of the sedimentation process of yeast
- Monitoring & logging of the yeast activity
- Monitoring & logging of the sedimentation process of DE (Kieselgur)
- Monitoring & logging of the sedimentation process of PVPP
Model TurbiLab-FS with optional software, dosage pump, temperature stabilized measurement chamber and magnetic stirrer upgrades the unit to a titrator. The Windows software controls the measurement cycles and the dosage pump for the reagents. This optional titration unit is particularly
designed for haze developing titrations.
