Heele Saccharimeter

Description
This half-shadow saccharimeter is marked “HEELE, BERLIN.” The signature refers to Hans Heele, a German artisan who made a wide range of precision optical and mechanical instruments. Heele worked closely with the Physikalisch-Technische Reichsanstalt in Charlottenburg, and won prize medals at the international exhibitions held in Chicago (1893), Paris (1900), St. Louis (1904), and Brussels (1910). The instrument was probably made before 1923, when Heele’s firm was acquired by Bamberg. Bowdoin College donated it to the Smithsonian in 1969.
The circle of this instrument is about eight inches diameter, finely graduated, and read by vernier and microscope. There are four glass observation tubes: one marked “100”; two marked “200”; and one, 200 mm long, with fitting for thermometer. An additional glass tube is marked “FRANZ SCHMIDT & HAENSCH / BERLIN” and “D.R.G.M. 60239.”
