The Manikin Breathing System is a high-precision experimental device designed to operate in combination with a 16-zone thermal manikin or as a standalone unit. It is used to simulate real human breathing conditions by accurately controlling inhalation and exhalation parameters. You can use this system to study aerosol particle distribution, air pollutant exposure, and cross-infection risks of airborne diseases under different environmental conditions. The system supports a wide range of scientific research and public health evaluation scenarios where realistic human breathing simulation is required.
