1. The structure and structure of the incubator affect the uniformity of the temperature in the work to a large extent. Because the structure is difficult to be completely symmetrical, the temperature uniformity is adversely affected. The door is at the front, and the air-conditioned room is behind the box. This structure has good symmetry, and it is relatively easy to achieve uniform left and right temperatures. These require the manufacturer to design a thermostat in a rigorous, reasonable and practical design concept.
2. It is the sealing property of the constant temperature box: if the tightness of the constant temperature box is not well done, it will cause the uniformity of the temperature box to be too large, for example, the door leaks, which will affect the temperature of the constant temperature box studio. This is the same. It takes a relatively mature technology from the manufacturer to do well.
3, the volume of the test sample is too large: if the detection of temperature deviation requires placing the sample in the working chamber, when the sample volume is too large, the test is placed too densely, or the placement method or position is not appropriate, the obstruction of air convection will also lead to Big temperature deviation.
4, the wall of the heat transfer: due to the thermostatic box wall heat conduction, resulting in leakage heat or leakage of cold and other losses, in order to compensate for heat loss, there will be air temperature difference, the air temperature will be higher than the box temperature, constant temperature The supply air temperature of the box will be lower than the working temperature inside the box. Due to the temperature difference of the supply air, the temperature inside the work chamber will be uneven.
What are the factors causing the uniformity of the incubator to be excessive? Through the detailed analysis of Shanghai Da Xiaobian, I believe that the user should have a certain understanding of it!
