Lot number: 421684
Winning bid: £125
The purpose of a hydrometer is to determine the specific gravity of a liquid. From this it is often possible to determine the composition or strength of the liquid. The Sikes hydrometer was, for very many years, the standard means of determining the alcohol content of spirits and hence the duty payable.
Includes a spirit tables pocket for Sike's Hydrometer booklet and a rather fragile booklet explaining who to use a sliding rule.
