✦ Synopsis

An experimental sensor allows continuous measurement and regulation of the water activity of a liquid medium, by measuring rhe relative humidity of a stream of air equiIibrated with the medium. The measurements were precise ( e 0.007 unities of water activity), and the small size of the sensor makes it-practical for use in a standard fermentor.
