Tightness of respirators masks and gas masks testing equipment
The aerosol particles with a certain concentration and particle size distribution are generated through the aerosol generator to pass through the mask body with the specified gas flow. The particle concentration before and after passing through the mask body is detected by the particle detection device. The filtration efficiency of the mask body for particulate matter is evaluated by the percentage of the particle concentration reduction after the aerosol passes through the mask body.

1. High-precision laser particle counter to detect the concentration of ions in the upstream and downstream of the sample and ensure the authenticity and accuracy of the upstream and downstream sampling of the sample.
2. The mist generation system uses nozzle to generate mist, which can meet the requirements of oil and salt aerosol generation at the same time, and can produce multi-dispersed particle size release, and the mist concentration adjustment is fast and stable.
3. Touch screen control, simple and intuitive operation, support remote maintenance.
4. The test result system automatically calculates and displays, prints and outputs.
5. It can automatically generate test reports and support historical data storage and query.
