Turbidity is measured in

Explanation:
Turbidity is determined by how much light is scattered by suspended particles, and a nephelometer measures this scattering, usually at a 90-degree angle. The standard way to express turbidity is in Nephelometric Turbidity Units (NTU), which arise from the nephelometric measurement method. Some sources refer to the concept as “nephelometric units,” but the formal, universally accepted unit name is NTU. Absorbance units relate to how much light is absorbed rather than scattered, so they don’t measure turbidity. Turbidity is therefore expressed as NTU.
