Nephelometer comes from the Greek word for cloud, nephos,
A more popular term for this instrument in water quality testing is a turbidimeter. However, there can be differences between models of turbidimeters, depending upon the arrangement (geometry) of the source beam and the detector. A nephelometric turbidimeter always monitors light reflected off the particles and not attenuation due to cloudiness. In the United Statesenvironmental monitoring the turbidity standard unit is called Nephelometric Turbidity Units (NTU)
