    摘要： The invention relates to a measuring cell for measuring optical properties of liquids, comprising a measuring chamber (16) which on one side is delimited by a transparent window (11) and a reflector (30), positioned on the opposite side of the measuring chamber (16), which reflects the light incident on it through the measuring chamber (16) and window (11) to the outside. According to the invention the measuring cell for liquids is especially easy to clean and allows for easily reproducible measurements for a long period if an additional transparent window (33) is arranged between the reflector (30) and the measuring chamber (16) which window delimits the measuring chamber (16) towards the other side.

    摘要： The invention relates to a bowl system for continuous testing of fluids, especially in the context of industrial processes, preferably by near infrared spectroscopy. The inventive system comprises a bowl (19) placed in a mounting rack (2) presenting a sample basin (22) with an inlet (23) and an outlet (24), a track of rays being directed to said sample basin. In order to facilitate testing, the invention is so designed that said mounting is placed in a housing fitted with an inlet connection (8) and an outlet connection (7) which run across the housing, and that ducts which can be quickly disconnected are provided between the housing inlet and outlet connections, on the one hand, and the sample basin inlet and outlet, on the other hand.

    摘要： The invention relates to a device and method for optically detecting the presence of ingredients of a pourable product by NIR-spectroscopy. In order to obtain reproducible measured results, the device is characterized in that the product flows in the direction of gravitational force, a valve (8) is fitted in the duct downs tream from the measuring window (6), and the valve can be moved into closed position by a control system, at least for the duration of measuring. The method is characterized in that the product flows in the direction of gravitational force past a measuring point, is retained downstream from the measuring point such that the flow comes to a standstill at the measuring point, and, after measuring, the product is removed from the banked-up stretch.
