The term 'nephelometric' is specialized and not easily understood without specific scientific knowledge.
Etymology
Nephelometric comes from an old Greek word nephelē meaning 'cloud' and the part -metric meaning 'measure', as in meter. So a nephelometric method 'measures cloudiness' in a liquid or gas by seeing how particles scatter light.
