WebTurbidity is measured in nephelometric turbidity units (NTU) or Formazin turbidity units (FTU), depending on the method and equipment used. Turbidity measured in NTU uses … WebTurbidity is caused by the individual particles of a substance within a fluid causing the fluid to range from mostly clear to hazy, or opaque. A haze meter measures the extent to which the turbid particles within a fluid scatter incident light, and outputs this measurement in a quantitative unit, the Formazin Turbidity Unit (FTU).
