1855 tr. R. Bunsen in London, Edinb. & Dublin Philos. Mag. 4th Ser. 9 122 It is necessary in the first place to obtain an exact determination of the coefficients of absorption; for this purpose I use an absorptiometer of the following construction.
1879 S. Wroblewski in Nature 25 Dec. 191/1 The absorptiometer which I have constructed for the determination of the coefficients of absorption, consists of glass through out.

1876 A. Schuster in Proc. Literary & Philos. Soc. Manch. 15 74 The instrument, which I have called absorptiometer, because it is intended chiefly for the determination of the absorption of light taking place in our atmosphere, consists of a table similar to that of a goniometer table.
1939 Thorpe's Dict. Appl. Chem. III. 305/2 Moll, Burger and Reichert..have devised a ‘spectroscopic absorptiometer’ which can be used at any part of the photographable spectrum.
1970 Nature 29 Aug. 876/1 A specially designed absorptiometer..has been found satisfactory for gamma absorption measurements.
2004 W. Hewitt Microbiol. Assay Pharmaceut. Anal. iv. 38 The absorbancies of these suspensions were measured using two absorptiometers.
