Resumo

In this study, we assessed ifthe turbidimeter calibration process affects turbidity data quality and theeffectiveness of field campaigns. Accurate results areobtained when new standard turbidity samples are preparedto calibrate the turbidimetersensor. Additionally, intervals of field campaigns greater than 15 days tend to be more feasible for cleaning, calibrating, and measuring actual data. Samples of formazine are prone to vary turbidity throughout the days resulting in statistically differentdata; thus, they lead to an overestimationof sediment concentrationreadingsdue to solutions deterioration that may affect the calibration process.
