Hydrometer A is 10" long and is for liquids denser than water, measuring specific gravity from 0.8 to 2.04 in increments of .02 and potential alcohol or Baume between -2 and 73 in increments of 1. It's calibrated to be used at an ambient temperature of 20°C/68°F. (Handy if you're fermenting your own happy juice at home.) Designed to be used at ambient temperatures of 15°C/59°F. There's a third scale in Chinese that probably measures the same things, but our Chinese is a little rusty. The jar (which is unmarked and would make a very slick big bud vase) is 50mm dia x 305mm tall with a 100mm dia base and will take a #10 rubber stopper (not included) if you feel the need to stopper it.

93481 SPECIMEN CONTAINER |
Born to be a sterilizing jar, this little straight-sided, clear glass cylinder has myriad uses outside the lab. Stands 4" tall on a hexagonal base and has a 1" OD, 3/4" ID mouth. No graduations, but a 1/2" x 3/4" ground patch on the side for labeling. Nothing to sterilize? It makes a very nice vodka glass, bud vase or candleholder.
