Assorted antique French measuring devices in their original tube boxes. These wine meters for example are designed to measure the percentage of alcohol in a liquid or distillate. I had to look it up. I can't decide if I like the glass meters with their script writing or the awesome tubes they came in. PAY ATTENTION to tube "A" as you can tell it is old based on the fact that the upper part of the tube is made with paste paper.
Measurements are for the length of the tube only. The meters of course will be smaller in order to close the tube.
A - 9.75" - Areometre Beaume used in Wine Making.
B - 11.25" - Densimetre De Gay Lussac used in wine making.
C - 9.5" - Areometre Baume used in wine making.
D - 10" - Areometre Baume used in wine making.
E - 11" - PESE-ACIDES used to measure the acidity in wine
