Precision vinometer determine alcohol 4-15% vol alcohol meter wine

Precision vinometer 4-15% vol.

For fast determination of alcohol content in fermented wines and juices.

Accuracy: 1° vol. %

Calibration based on an alcohol-water solution of 10° vol.%

Prismatic capillary with blue background for easy reading, even in white wines !

Scale in 1% increments.

Length:   13 cm

Instructions for use:

Pour a small amount to of the wine to be measured into the funnel.
The liquid column must never be interrupted by air bubbles or dirt
! As soon as the first droplets drip from the pointed end
, close the opening with your finger. Then turn
the measuring instrument over and place it on the table with the funnel opening facing down
. Remove your finger from the opening, the liquid in the
capillary tube will sink rapidly and when stopped will give the alcohol content in
percent by volume.

The measurement accuracy depends on the cleanliness of the tube, the residual sugar
content of the wine to be measured, the temperature, etc. ( sweet wines give
a faulty measurement more quickly and must therefore be diluted).

Example

mix 10ml of wine with 10ml of water and then measure.
The value obtained, e.g. 6 is multiplied by 2.
The alcohol content is then 12.

Conversion from percent by volume to percent by weight:

1 percent by volume = 0.8 percent by weight = 8g of alcohol per liter

So: a wine at 15°C (=percent by volume) contains 120g of alcohol per
liter of wine.
