Product Usage:
SG688 melt blown cloth filtration efficiency performance tester is used to test the filtration efficiency of melt blown cloth, daily protective masks, medical masks, and respirators for particulate matter.

Features:
1. Equipped with a laser dust particle counting sensor to measure the number of aerosol particles in the upstream and downstream of the filter material at the same time, and accurately measure the filtration efficiency of the filter material.
2. Equipped with an aerosol generator to measure the filtration efficiency of particulate matter to meet users' testing requirements for filter materials.
3. Equipped with aerosol and neutralizing gas flow meters to control the number of salt particles in aerosols,
4. Equipped with a high-voltage anti-static air nozzle for neutralizing static electricity in aerosols.
5. The gas that neutralizes the aerosol concentration is heated to 35 degrees and then mixed and transported to the upstream of the filter material.
6. Equipped with a high-precision digital flow sensor for measuring the gas flow during testing.
7. High-precision differential pressure transmitter to test the airflow resistance on both sides of the sample.
8. Use a vacuum pump to generate the negative pressure required for testing, quiet and no vibration.
9. The upstream and downstream aerosols are discharged into the air after passing through the filter to prevent the air near the instrument from being polluted.
10. Equipped with 14-inch display, industrial computer operating software and control hardware.


11. Pneumatic clamps hold the samples, and have a mechanical anti-pinch design to prevent operating errors and ensure safety.
12. The computer comes standard with a micro printer to output test reports.


13. The electrical connection is safe and reliable to protect the safety of operators and instruments.

According to the standard:
GB 2626-2019 "Respiratory protective equipment self-priming filter anti-particulate respirator" (salt aerosol)
