LB-3307 mask filtration efficiency testing device
Product introduction
LB-3307 mask filtration efficiency testing device is used to test the protection effect and filtration efficiency of daily protective masks and respirators on particulate matter. It is applicable to medical device inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, textile inspection center, hospital, mask and respirator manufacturing enterprises, etc.
Standards-compliant
GB 32610-2016 "Technical Specification for Daily Protective Mask"
GB 2626-2006 "Respiratory Protective Equipment-Self-priming Filtration Anti-particulate Respirator"
GB 19082-2009 "Technical Requirements for Medical Disposable Protective Clothing"
GB 19083-2010 Technical Requirements for Medical Protective Masks
YY 0469-2011 Medical Surgical Mask
Performance characteristics
1. The cold aerosol generator is used to generate continuous and stable aerosol particles, which is convenient for filling solution.
2. High precision laser sensor is used to measure aerosol concentration.
3, the whole process of particulate matter leakage prevention design, to protect the safety of laboratory personnel.
4.Two sets of aerosol generators: saline aerosol generator and oily aerosol generator.
5.Pneumatic clamp is equipped with protection device, which is safe and convenient to use.
6. Configure precision flowmeter and laser dust particle counter.
7. Detection range of filtration efficiency: 0-99.999%.
8. Filter efficiency detection flowmeter range (10-100)L/min, with accuracy of 2.5 grade.
9. Control system: friendly man-machine interface controls the test process and automatically collects data.
10. The system automatically tests the gas concentration and automatically calculates the filtration efficiency. Can save, output, query and print test data.
11. The color touch screen is easier to operate.
