Multi-Wavelength Calibration of a Low-Cost High-Range Turbidimeter: Analysis of the Dispersion Regime.

ABSTRACT: Turbidimetry, a method for assessing fluid clarity by quantifying suspended particle levels, plays an important role in various fields, including environmental surveillance, sediment measurements, water quality management, and diverse industrial sectors. Various optical instruments are commercially available, normally called turbidimeter. However, no generic calibration that can be used to convert the turbidimeter output to NTU is possible. This work presents the development of a low-cost multiwavelength turbidimeter designed for high-range turbidity measurements (0.5-4000 NTU) in visible and near-infrared spectra (500-1000 nm). Using formazin solution as a turbidimetric standard and introducing the calibration factor concept, we were able to determine the identification of multiple
