This invention concerns a device ( 1 ) for the determination of air content, the air separation behavior and the surface foam formation of oils, in particular of transmission oils with an air-oil mixer ( 2 ) and a differential pressures sensor ( 3 ). A conveyor system ( 4 ) transports the oil through pipe lines ( 5 ) of the air-oil mixer ( 2 ). A compressed air port ( 6 ) is provided, which transports air into the pipe lines ( 5 ), of the air-oil mixer ( 2 ). A Venturi pipe ( 9 ) is installed in one of the pipe lines ( 5 ), and the differential pressure sensor ( 3 ) records, through at least two separate drill tubes ( 7, 8 ) in the conveyor system of the oil at the Venturi pipe ( 9 ), differential pressures in the oil.
