Product Features

1. The cold-generating aerosol generator is used to produce continuous and stable aerosol particles, and the filling of the solution is simple and convenient.
2. Two sets of high-precision aerosol particle detection sensors are used to measure the upper and lower chambers simultaneously.
3. Configure salt particulate aerosol generator.
4. Equipped with aerosol particle electrostatic charge neutralization device.
5. Configure high-precision digital gas flow sensor to accurately measure gas flow.
6. Configure industrial-grade temperature and humidity sensors to accurately measure the ambient temperature and humidity in real time. (Test conditions: 25±5℃ 30±10% RH)
7. 7-inch touch screen, simple and clear operation.
8. Pneumatic fixture, easy to load and change samples.
9. Pumping and exhausting integrated silent vacuum pump without external air source.
10. High-precision pressure gauge and flow control valve can adjust the aerosol concentration.
11. The micro printer can print test data.
12. Intelligent configuration such as leakage protection, overload protection, power-down save, etc., effectively protect the safety of use.
13. Dedicated test software, can be connected to a computer (optional)
