Abstract
The invention relates to a method and apparatus for measurement of total water content in a liquid. According to the method, the relative water content (aw) of the liquid is measured in a first measurement step at a first temperature (T). According to the invention, the temperature of the liquid under measurement is altered from the first temperature (T) and the relative water content is measured in a second measurement step at the second, altered temperature (T), whereby, based on these at least two measurement values (aw()T, aw()T), the total water content is determined from the temperature dependence of water dissolution into the liquid under measurement.
