History and use
Bartholomew Sikes invented this style of hydrometer in 1802, in response to a competition held by the Board of Excise in London. Sikes’ hydrometer remained the legal standard instrument for excise purposes (mainly for alcohol testing) until 1907.
This example was manufactured by Robert Bretell Bate (known as ‘Bate of the Poultry’) in London in the early 1800s. Bate originally trained as a haberdasher and later in his career patented spectacle designs. Bate made the first Sikes hydrometers after the competition and supplied the Board of Excise. Each hydrometer was individually numbered; this is number 7260.
