DEVICE FOR MEASURING AT LEAST ONE VOLATILE COMPONENT OF AN AQUEOUS SOLUTION, IN PARTICULAR FOR MEASURING ALCOHOL

摘要

A device for measuring at least one volatile component of an aqueous solution, in particular for measuring alcohol, comprises a measurement chamber (2) having on opposite sides a sensor (5) for measuring the volatile component and a membrane (3) which is permeable to the volatile component and closes a chamber opening (4), as well as an outgoing air conduit (9) connected to the measurement chamber (2). In order to create advantageous measurement conditions, the measurement chamber (2) is connected at the top to the outgoing air conduit (9) and at the bottom to a fresh air conduit (8), and accommodates a heat source (10).
