Description
Hydrometers are instruments for measuring the specific gravity of liquds at a specific temperature. They can also be called 'lactometers', which are hydrometers used specifically for milk. This hydrometer is part of a collection acquired from the University of Reading's Department of Food Science Processing Laboratories. It has a narrow bulb painted half black. It is used for measuring specific gravity at 60° F, on a scale of 1800-2000 in units (not specified) of ten and two.
