Large capacity aerosol sampling device

Large capacity aerosol sampling device

Product introduction           

The main function is to sample the air through the filter and measure the activity of the retained aerosol. The unit sends warning and alarm messages when activity exceeds predefined levels. An aerosol filter coupled to an air pump is capable of accumulating large quantities of airborne particles on small surfaces so that their radioactive content can be determined with good measurement efficiency.
