The tester introduction
The mask particle protection effect and filtration efficiency tester is used for testing the protection effect and filtration efficiency of daily protective masks and respirators against particles. It is suitable for medical equipment testing center, safety protection testing center, labor protection testing center, drug testing center, disease prevention and control center, textile testing center, hospitals, mask and respirator manufacturers, etc.
Equipment use
Mask particle protection effect and filtration efficiency tester for daily protective masks and respirators on the particle protection effect and filtration efficiency test. Applicable to medical equipment inspection center, safety and protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, textile testing center, hospitals, masks and respirators production enterprises, etc.
