The uniformity and stability deviation of animal respiratory tract for gas is within ±8%, for liquid aerosol is within ±10%, while for dust aerosol is within ±20%, which conforms to technical requirements of OECD guidelines.

Aerosol particle size distribution is MMAD1-3μm, GSD1.5-3.

The temp, humidity, oxygen and carbon dioxide concentration of exposure chamber during test meet requirements of inhalation guidelines.

One cage for one rat inhalation exposure structure can perform 20-80 rats test simultaneously.

Real-time monitor temp, humidity, pressure difference, oxygen and carbon dioxide concentration of exposure chamber during tests. Parameters can be controlled according to requirements of laboratory, e.g., air inlet flow, dilution flow, sampling flow, exhaust flow, exposure time, remaining time, etc.
