Urinometer

Description
Urinometers are used to measure the specific gravity of urine, a measurement of its density. Specific gravity of urine fluctuates with the concentration of dissolved substances contained in the sample. Urine with low specific gravity can be a sign of diabetes or kidney problems.
The urinometer has a graduated scale divided into four divisions. The upper most division is marked with the letter W: this is the level where the instrument rests in pure water. The next division is maked by the letter H: this is the level where the instrument rests when immersed in urine from a healthy person. The letter S indicates strong but not as healthy as H. Diabetes is indicated when the instrument rests in the lower most division.
