Saccharimeter

Definitions

  • Webster's Revised Unabridged Dictionary
    • n Saccharimeter An instrument for ascertaining the quantity of saccharine matter in any solution, as the juice of a plant, or brewers' and distillers' worts.☞ The common saccharimeter of the brewer is an hydrometer adapted by its scale to point out the proportion of saccharine matter in a solution of any specific gravity. The polarizing saccharimeter of the chemist is a complex optical apparatus, in which polarized light is transmitted through the saccharine solution, and the proportion of sugar indicated by the relative deviation of the plane of polarization.

    • n saccharimeter An optical instrument used to determine the quantity of sugar in a solution. It is based upon the fact that sugar-solutions have the power of rotating the plane of polarization of a ray of light transmitted through them. Certain kinds of sugar rotate the plane to the right (dextrorotatory), as grape-sugar (dextrose) and cane-sugar; with others, the rotation is to the left (levorotatory), as levulose; further, the amount of angular rotation varies with the strength of the solution. There are many forms of saccharimeter, some of which measure directly the amount of rotation caused by a layer of the solution of given thickness; others balance the rotation of the solution against a varying thickness of some rotatory substance, as a compensating quartz plate.
    • n saccharimeter A hydrometer for testing saccharine solutions, used by brewers; a saccharometer.

In literature:

Any cider that will grade 18 or 24 with the saccharimeter in the fall of the year, when it is made, will make good vinegar.
