A » The Nephelometric Turbidity Unit (NTU) is a measure of the turbidity, or cloudiness, of a fluid caused by suspended solids. It is commonly used in water quality testing to assess the clarity of water. A higher NTU value indicates more suspended particles, reducing water clarity. Turbidity is measured using a nephelometer, which assesses the scattering of light by particles in a water sample.
