Negative pressure balance safety weighing cabinet

GR-T series from GR-TNegative pressure balance safety weighing cabinetIt is designed specifically for weighing toxic and harmful chemical reagents and solid powders in laboratories. The equipment comes with a fan and high-efficiency filter, which can effectively adsorb toxic and harmful gases generated during the weighing process due to the volatilization of chemical reagents. It can also be equipped with a HEAP filter to adsorb solid powders generated during the weighing process, preventing experimenters from inhaling chemical waste gas or solid powders during the weighing process and causing harm to their bodies, effectively protecting the occupational health of workers.
