Hydrometer chimney
Revision as of 23:46, 23 August 2017 by Uncle Jesse (talk | contribs)
A tall, narrow, cylindrical vessel used to float a hydrometer in the liquid to be measured. Using this vessel requires a smaller liquid sample than using, for example, a one gallon open-mouthed jar, as hydrometers tend to be rather long and must be floated in a deep vessel.
