The invention concerns an immersion device 10, 20 for collecting a slag sample and measuring a molten metal parameter, wherein the immersion device 10, 20 comprising an inflow conduit 5, 25 for directing the molten slag 18 to a slag sample chamber 7, 27 and a measuring element 1, 21 for measuring the parameter of the molten metal 19, wherein the inflow conduit 5, 25 and the measuring element 1, 21are both arranged in the top area of an immersion end of the immersion device 10, 20 and/or both facing towards an immersion direction 17. The immersion device 10, 20 is composed such that during immersion in the immersion direction 17 into the molten slag 18 and then the molten metal 19, the molten slag 18 enters an external portion of the inflow conduit 5, 25 and is directed through an inner portion of the inflow conduit 5, 25 to the slag sample chamber 7, 27. Reliable slag collection and molten metal measurement also in a converter can thereby be achieved. The invention also concerns a method of collecting a slag
