WebFeb 17, 2024 · For this, the optical sensor is located at an angle close to 90 degrees. This technique allows for shallow turbidity values to be calculated, so it is frequently used in potable water. The measurements obtained using this method are expressed in nephelometric turbidity units (NTUs). They usually take values in the range of 0.05 … Because optical properties depend on suspended particle size, a stable synthetic material called "Formazin" with uniform particle size is often used as a standard for calibration and reproducibility. The unit is called Formazin Turbidity Unit (FTU).Nephelometric Turbidity Units (NTU) specified by United … See more A nephelometer or aerosol photometer is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light … See more The main uses of nephelometers relate to air quality measurement for pollution monitoring, climate monitoring, and visibility.
