Related to a method of measuring the concentration of suspended particles in a liquid by analyzing the light scattered by those particles.
The nephelometric method is often used in laboratories to determine the turbidity of water samples.
Nephelometric → It is formed from "nephelo-" (from Greek "nephele", meaning cloud) and "-metric" (from Greek "metron", meaning measure). The word refers to the measurement of cloudiness or turbidity in a liquid, particularly in relation to light scattering.
Think of measuring 'cloudiness' ('nephele') in a liquid, which is what nephelometric means.
