Operation method:

1. The continuous and stable aerosol particles are produced by using a cold generated aerosol generator, which is convenient for filling solution.
2. High precision PM2.5 sensor * 2 imported from USA was used to measure aerosol concentration.
3. The whole process is designed to prevent the leakage of particles to protect the safety of laboratory personnel.
4. 2 sets of aerosol generator: salt particle aerosol generator and oily particle aerosol generator (select salt particles or select at the same time).
5. Electrostatic charge neutralization device is equipped with aerosol.
6. Pneumatic fixture is equipped with protection device, which is safe and convenient to use.
7. Equipped with glass rotor flowmeter, vacuum pump, laser dust particle counter.
8. Control system: PLC and touch screen control.
9. It can automatically calculate assist and filter efficiency, save, output, query and print test data.
10. Touch screen control, simple and intuitive operation.
