2) Continuous measuring mode can be used to observe the process of stabilizing turbidity values. It’s also suitable for a sample solution which precipitates faster, since it records every measuring value and calculates the average value. 5.5 Measurement Notes Turbidity is a very complex analytical measurement which can be affected by many factors. -
