Nephelometric Turbidity Ratio Unit ( NTRU): EPA-based unit that uses … 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).
WebThe calibrated units of measure on the tube were called Jackson Turbidity Units (JTU). Nowadays, the most commonly used unit for turbidity is the Nephelometric Turbidity Unit (NTU), with the occasional use of the Formazin Nephelometric Unit (FNU) that was developed in 1962 by using formazin polymer solution as a standard reference.
