Lactometer vs. Urinometer — What's the Difference?

A device used to measure the specific gravity, and therefore the richness, of milk.

An Urinometer is a simple piece of equipment for determining urine specific gravity. A typical urinometer is composed of a float, a weight, and a stem.

A device that estimates the cream content of milk by measuring its specific gravity.

A hydrometer for measuring the specific gravity of urine.

An instrument for estimating the purity or richness of milk, as a measuring glass, a specific gravity bulb, or other apparatus.

A hydrometer used to measure the specific gravity of urine.

A small hydrometer for determining the specific gravity of urine.
