In the production processes of pharmaceuticals, biopharmaceuticals, and fine chemicals, powder weighing and batching are critical steps related to product quality and production safety. During the weighing process, the risk of powder dust escape and cross-contamination, as well as the maintenance of a stable clean environment, remain core pain points for industry compliance and safety management. The weighing hood controller, as the "central brain" of the negative pressure weighing hood, becomes a core piece of equipment for solving these pain points and ensuring production complies with GMP and other industry standards through precise airflow control, multi-dimensional status monitoring, and automated linkage control.
