DEVICE FOR MEASURING ONE OF AT LEAST TWO VOLATILE COMPONENTS OF A LIQUID, IN PARTICULAR A FERMENTATION LIQUID

摘要

In this device comprising a housing (2), a sensor (3) for measuring volatile constituents located in the housing comprising a permeation membrane (6) applied to a support body (5) and separating the liquid opposite a channel (7) of a carrier gas connected to an inlet pipe (9) and to an outlet pipe (11), the body (5) forms a closure plug for an opening (4) of the housing covered by the membrane applied on a front face of the plug, and formed of at least two layers (6a, 6b) having a different resistance crossing for the volatile constituents. BR/ Application in particular to the measurement of fermentation liquids .
