This International Standard specifies alcoholometers incorporating a thermometer (thermo-alcoholometers) and alcoholthermohydrometers, suitable for general alcoholometric purposes. The details specified are, as far as alcoholometer and hydrometer specifications are concerned, in conformity with ISO 387. NOTE - The scale of alcoholometers is adjusted to allow direct readings of alcohol contents of alcohol-water mixtures. The scale of alcohol-hydrometers is graduated in density units (for example kglm$ and their nominal range is particularly adapted to the requirements of alcoholometry.
