Automatic device for determining alcohol content in moistening media for printing machines, etc.

摘要

The device has a chamber (2), into which the specimen (4) to be measured is passed. The specimen is rapidly cooled (3) in the chamber to below its freezing point until the specimen becomes solid. The specimen is reheated to the freezing point through crystallization heat. Its temperature is measured (5) immediately after this temperature step and is used as a measure of the alcohol content. The thermoelectric effect is used to cool the specimen chamber.
