Adopt stainless steel double static pressure chamber structure and special primate mask, it can perform inhalation tests for 6-10 primates simultaneously.

The evenness and stability error of each exposure port's mass concentration during tests 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 inhalation guidelines.

Waste gas can fully meet Safety Emission Standards after treatment.

The unique structural and air pressure control of exposure system ensures tight protection. Protection alarm is effective against abnormal temp, abnormal pressure difference and gas leakage.
