Formazin Turbidity Units (FTU): see Nephelometric Turbidity Units 
 
Indexing a Cuvette: The United States Environmental Protection Agency (US EPA) recommends that cuvettes 
used for turbidimeter calibration or sample measurement be indexed. To index a cuvette with a sample in it, 
slowly rotate the cuvette throughout one complete revolution (360°). While rotating the sample cuvette, observe 
the display and locate the position that the cuvette is in which provides the lowest turbidity reading. This position 
is the indexed position of the cuvette
 
Nephelometric Turbidity Units (NTU): Unit of measure used when comparing the light scattered by a liquid media 
to the light scattered by a known concentration of Formazin Polymer. This unit of measure is recognized as a 
measure of the optical clarity of an aqueous sample.  NTU is the accepted unit of measurement for turbidity. 
 
Turbidity: 1) A measure of the attenuation of a radiant flux as it passes through a liquid media.  2) Optical clarity of 
a liquid, 3) a phenomena caused by the presence of undissolved matter in liquid media.
