Detailed explanation-1: -Turbidity is the measure of relative clarity of a liquid. It is an optical characteristic of water and is a measurement of the amount of light that is scattered by material in the water when a light is shined through the water sample. The higher the intensity of scattered light, the higher the turbidity.

Detailed explanation-2: -Turbidity Meters technically known as nephelometers – emit light and measure the amount scattered by particles in the sample. The units depend on the wavelength of the light and the angle of the detector(s)13; the most common units are Nephelometric Turbidity Units (NTU) or Formazin Nephelometric Units (FNU).

Detailed explanation-3: -VOICEOVER. Water clarity – or turbidity – is a measure of underwater visibility in rivers and streams. This measurement indicates how much fine sediment, algae and other particles are in the water column.

Detailed explanation-4: -How To Measure Turbidity In Water? A turbidimeter is used to analyze the turbidity in drinking water. A minimum of two readings are taken to meet calibration standards and improve accuracy. A nephelometer (turbidity meter) is used and either NTU or FTU units can be used.
