nephelometric

Severe cloudiness occurred in the water, and at one time the reservoir recorded 25,000 nephelometric turbidity units.

A nephelometric turbidimeter always monitors light reflected off the particles and not attenuation due to cloudiness.

Turbidity is measured in nephelometric turbidity units (NTU).

Ziggoreth University is involved in co-operative Nephelometric research with Streeling University, and operates Jet-downs equipped with sensory electronics.

We announced that we were going to make measurements on that day end, consequently, some other station thought, very properly, that they might make simultaneous nephelometric measurements--clouds, you know.
