After placement is completed, place the sample on the sliding plate 62, and then close the sealing door 2. The detector inside the shell 1 detects the humidity and temperature inside the shell 1. There is a heating mechanism in the water tank 3. When the temperature inside the shell 1 is low, the heating mechanism heats the water inside the water tank 3, and the water vapor is sent into the air inlet column 4 by the water tank 3. The water vapor moves upward along the air inlet column 4, and the water vapor passes through the air inlet column 4 and the isolation component 5 and moves to the placement component 6 to heat the space where the placement component 6 is located. Since there is a certain distance between the fixed plate 61 and the inner wall of the shell 1, both sides of the fixed plate 61 can be heated by the water vapor, and there is no temperature difference on both sides of the fixed plate 61.
