The same material that is transported by the flow must be used for the turbidimeter
calibration, and the samples obtained must have the same amplitude of the SSC that may occur in the flow, to avoid the extrapolation of the calibration curve.
Upon completion, 30 mL of suspension was withdrawn from the centre of the flask, ensuring that the sediment at the base of the flask was not disturbed, transferred to the turbidimeter
, and the turbidity of the suspension was recorded in NTU.
In this article it was shown how an integrated circuit of amplified photodiode might speed up development of turbidimeter
Temperature and water quality parameters, including turbidity (nephelometric turbidity units, NTU, 2100P Turbidimeter
, Hach Company, Loveland, CO), dissolved oxygen (mg [O.
The fluid was then vortexed to obtain a uniform cell suspension and was read in a turbidimeter
The turbidity was measured using the Turbidimeter
(Orbec Analytical Systems Inc.

Suspension was prepared at appropriate inoculums density using turbidimeter
depending on the Inoculation Fluid (IF) used and types of microbes.
One was used to measure the turbidity of the clarified water and the other was used to measure the turbidity of the filtered water, in both cases through the use of 5 electrovalves that were programmed to control the water pass from each filter to the turbidimeter
The system comprises a turbidimeter
and a converter.
The Turbidity Monitoring System comprises a turbidimeter
and a converter.
Turbidity was measured in the field with an Aguafluor handheld fluorometer and turbidimeter
(Turner Designs, model 8000-001, Sunnyvale, CA, USA).
