WebTurbidity is commonly measured using a nephelometer which uses a light beam (source beam) and a light detector (usually at a 90° angle) set to one side of the source beam. The units from a calibrated nephelometer are called Nephelometric Turbidity Units (NTU). 1 NTU: Common measurement for tap water. WebTurbidities measured according to the first method are presented as nephelometric turbidity units (NTU). The results typically range between <0,05 NTU and 400 NTU. Depending on the instrument design, it can also be applicable to waters of higher turbidity. There is numerical equivalence of the units NTU and formazin nephelometric unit (FNU).
