Bookmark this page Sikes's Hydrometer

  • Maker: R. B. Bate, Poultry, London
  • Date: c1840
  • Description and Notes:

    This is a full size set of the Sikes's hydrometer completed with float, weights, thermometer, and case. The base plate of the thermometer is made of ivory, so is the name plate on the solid mahogany case.

    Based on the information provided on this page, the first Sikes hydrometers to be made were from R. B. Bate (w1808 ~ d1847), who was the son-in-law of Sikes and had an actual or near monopoly until the 1840's as supplier to the excise. Several thousand of them have been made by him during the time. The one showing here is numbered 5511, and has been readjusted by W. Reeves, 146 Minories, London (c1850). The adjustment made by Reeves apparently was on the thermometer, which was originally made by J. Long, according to Directory of British Scientific Instrument Makers 1550-1851, this might be James Long, Joseph Long I or II, all were opticians working in London, from 1781 to 1846.
