A closure mechanism for an electromagnetically sealed measuring station, which comprises a test chamber, a door for closing the test chamber, and an electromagnetic seal, which is fitted to a door frame of the test chamber. The door is moved initially in a linear manner away from the test chamber and after that pivoted in a rotating movement. The closure mechanism according to the invention then seals a measuring station electromagnetically if an electromagnetic seal is fitted in a peripheral groove in the doorframe of the test chamber, and the door provides a peripheral rebate, which engages in the groove in the doorframe.
