LFY-719 Leakage Testing Device

Main purpose

This is used for testing the particle leakage rate of masks, face shields, respirators and gas masks. It is applicable to labor safety protection inspection centers, medical device and pharmaceutical inspection centers, disease control centers, textile testing centers, mask and face mask enterprises, etc. 
Technical Specifications

1. The gas generation volume of NaCl particulate aerosol: not less than 100 L/min 
2. Concentration of NaCl particulate matter: (10 ± 2) mg/m³ 
3. Air dynamics of NaCl particulate matter: Particle size distribution ranges from 0.02 to 2 micrometers; the mass median diameter is approximately 0.6 micrometers. 
4. Dynamic range of the particulate matter detector: 0.001 - 200 mg/m³; Accuracy: 1%; Response time: no more than 500 ms 
5. Sampling pump adjustment range: 0.50 - 4 L/min 
6. Sampling flow rate of particulate matter: 1 - 2 L/min 
7. One set of particulate matter concentration detection device 
8. Equipped with a dedicated computer and software for controlling the test. The software supports data storage, query, export, etc. 
9. Real-time display of leakage rate, automatic calculation of leakage rate 
10. The testing chamber is airtight and meets the requirements of standard tests. The test subjects perform their actions according to the standard procedures.
