Vinomer ( aerometer ) precision instrument made in Ukraine.
Vinomer - saharomer for measuring the sugar content up to 12% alcohol and 25% liquids.
Hydrometers
- (from the Greek . Araios - liquid and metreo - measure ) designed to
measure the density , relative density and the concentration of
substances in two-component solutions.
A
hydrometer is a glass tube , extended lower part of which is filled
with ballast - a clean, dry metal shot , filled with the resin layer of
wax or other binder - with a melting point of not lower than +80 ° C. On
the top ( narrow ) part of the hydrometer marked scale , graded in
terms of density or percentage , depending on the purpose of the
hydrometer . The
smaller the density of the liquid , the deeper it sinks into the
hydrometer , so the upper division of the scale corresponds to the
smallest , and the lower - the highest density. Readings are measured at the lower meniscus .
Depending on the purpose of the following kinds of hydrometer :
• General purpose with a scale graduated in units of density ;
•
for the measurement of substances in solutions with bicomponent scale
graduated in percentage of the solute ( by volume or weight);
•
special purpose for measuring the density of oil, sea water , milk, to
determine the strength of aqueous-alcoholic solutions , with the scales
showing the concentration of solutions in percent ( by volume or
weight);
• siphon hydrometer to measure the density of the electrolyte in batteries.
Measurements with the hydrometer is usually made at a liquid temperature +15 or +20 ° C. Determination
of density hydrometer volatiles are not allowed , since the vigorous
evaporation of the liquid temperature decreases .
Vinomer
- a device designed to determine the concentration of alcohol in the
finished wine is not fastening , as well as to measure the percentage
sodezhaniya sugar syrups , fruit juices , Braga, wines and other aqueous
solutions.
