The invention relates to a device for measuring the air density of a building envelope (1), having at least one building opening (2) leading to the atmosphere, comprising at least one blower (4a, 4b, 4c, 4d) surrounded by a housing (3), wherein the housing (3) has an air inlet side (5) and an air outlet side (6) and can be connected to the building envelope (1) in a sealing manner via connection aprons (7) around the building opening (2). The invention addresses the problem of improving a generic device in such a manner that a more exact measuring result than the prior art is possible without mounting and dismounting the housing (3). According to the invention, the problem is solved by a device in which the at least one blower (4a, 4b, 4c, 4d) is pivotably arranged within the housing (3), wherein the air inlet side (5) and the air outlet side (6) change by means of swivelling. |
