Features
l Using a cold aerosol generator to
produce continuous and stable aerosol particles, convenient for filling the
solution.
l Measurement of aerosol concentration
using a high-precision PM2.5 sensor.
Anti-leakage design of whole particles to protect the safety of laboratory
personnel.
2 sets of Aerosol generator：Salty aerosol generator and oily aerosol
generator.
l Equipped with aerosol particle
neutralization device.
l The pneumatic clamp is equipped with a
protection device, which is safe and convenient to use.
l Configure temperature and humidity
sensor, real-time display of ambient temperature and humidity（Temperature and humidity
requirements：25℃±5℃，30%RH±10%RH）。
Equipped with glass rotor flowmeter, vacuum pump, laser dust particle counter.
l Control system: The computer controls
the test process, automatically collects data, and configures a special computer
and test software.
The computer automatically tests the gas concentration and calculates the
filtration efficiency. It can save, output, query and print the test data.
