Description

Technical Field

[0001] The utility model relates to the technical field of a constant temperature and humidity weighing device with uniform air inlet, in particular to a constant temperature and humidity weighing device with uniform air inlet. Background Art

[0002] After environmental control atmospheric sampling, it needs to be weighed by a micro instrument and meet the temperature and humidity conditions within the specified range. In the past, a constant temperature and humidity cabinet was used for balancing after meeting the conditions. However, the conventional method can no longer meet the requirements of filter membrane weighing analysis. It is necessary to cooperate with a precision balance at the millionth level to achieve the conditions for filter membrane weighing. At the same time, there are also problems such as large occupied space and too high operating cost. The problem of secondary pollution caused by opening the weighing device during the weighing process also needs to be taken seriously.

[0003] After retrieval, it is found that a constant temperature and humidity weighing system is disclosed in the Chinese patent with the application number 202021969307.X, including a weighing box. The left and right side plates, which are relatively arranged in the side plates of the weighing box, are a double-layer structure formed by inner and outer plates. An insulating and moisture-proof layer, a cold water flow channel and an air duct are successively arranged from outside to inside in the inner cavities of the left and right side plates. A plurality of air outlets are opened on the inner plates of the left and right side plates. The number of air outlets in the upper and middle parts of the left and right side plates is less than the number of air outlets in the lower parts of the left and right side plates. A drying chamber is arranged outside the weighing box at the position corresponding to the through hole, and an isolation door covering the through hole and hermetically connected to the weighing box is arranged at the position corresponding to the through hole.
