Brannan’s range of marine, laboratory and educational hydrometers is extensive. We supply British manufactured hydrometers that measure density or specific gravity of a vast assortment of liquids and minerals, including alcohol; salt; sugar; urine; milk… Brannan understand that precision accuracy can only be achieved if the measuring instruments are manufactured out of the very best materials, and this is why our hydrometers are made from soda glass with steel shot ballast and synthetic wax resin.

Our range for the petroleum industry is broad, and includes ASTM hydrometers which are made using the API (American Petroleum Institute) scale.
