Saccharimeter,

Chambers's Encyclopaedia, Volume 9: Bound to Swansea, p. 62

Saccharimeter, or SACCHAROMETER, an instrument for determining the quantity of sugar in liquids, especially brewers' and distillers' worts. In principle it resembles the hydrometer (see SPECIFIC DENSITY), used for ascertaining the strength of alcoholic liquids. It consists of a hollow sphere or oval of thin brass, with a graduated stem and a hook so placed opposite each other that when placed in water it floats, and the graduated stem stands upright on the top, and the hook is below, for the purpose of appending weights. The degree to which the stem sinks gives the means of calculating, by tables prepared on purpose, the proportion of saccharine matter present in the liquid.
