turbidimetern.
/təːbɪˈdɪmɪtə/ Chemistry and Biology.
An instrument for determining the turbidity of a liquid from the decrease in the intensity of a beam of light passing through it.

1905 Water Supply & Irrigation Papers (U.S. Geol. Surv.) No. 151. 26 The needs of the Survey were found to be met in a satisfactory manner by the use of a turbidimeter devised by Mr. Daniel D. Jackson.
1920 Jrnl. Biol. Chem. 42 191 Turbidimeters and nephelometers are instruments designed for practically the same purpose.
1973 Sci. Amer. June 112/1 Extinction turbidimeters are doubtless the simplest instruments that have been devised for measuring the concentration of solids in suspension. They are based on the principle that turbidity is inversely proportional to the minimum length that a column of fluid must have in order to extinguish at one end of the column a source of light at the other end.
