    Turbidity meter applications

    Tips: What units are used to measure turbidity?

    Turbidity is typically measured using nephelometric turbidity units (NTU) or formazin turbidity units (FTU). Both NTU and FTU are widely used units to quantify the degree of turbidity in a liquid sample.

    Nephelometric turbidity units (NTU) are commonly used in drinking water and wastewater treatment applications. The measurement is based on the scattering of light by particles suspended in the water. An instrument called a nephelometer measures the amount of light scattered at a specific angle, and the resulting measurement is expressed in NTU.

    Formazin turbidity units (FTU) are often used in laboratory settings. FTU is a unit of measurement that quantifies the turbidity of a liquid sample by comparing it to a standardized suspension of formazin particles. The turbidity of the sample is determined by measuring the amount of light scattered by the suspended particles and comparing it to the scattered light from the formazin standard.

    Both NTU and FTU provide a numerical value that indicates the clarity or cloudiness of a liquid sample. The higher the NTU or FTU value, the greater the turbidity or cloudiness of the sample.
