In order to prevent infection at the medical site, and during labor operations, workers must be protected from inhalable hazardous substances in the workplace, and respirators such as masks must be worn during operations.
Combine your facial features to choose respirators such as respirators, and evaluate the closeness between respirators such as respirators and the face to check whether there are gaps or leaks that put workers at risk. The mask fit tester can quickly complete the fit test of respirators such as masks to ensure that it provides good protection performance. Safety experts will also formulate protection schemes and standards and regulations based on the results of the tightness experiment. It is widely used in hospitals, manufacturing plants, production sites, fire-fighting workplaces, and other official inspection agencies.
