[0002] In some industries such as medicine, food, dyes, pesticides, organic pigments, surfactants, and spices, very high requirements are placed on product purity, which requires very strict control over the quality of raw materials. Therefore, the demand for weighing in a constant temperature and humidity environment is increasing, and the application areas are becoming wider and wider, especially for some low-concentration objects. The weighing process is usually carried out inside a constant temperature and humidity test chamber.
