Abstract
An aerosol concentration sensor calibration device includes a mixing column, a sensor, and a collection vessel. The mixing column extends in a vertical orientation between an inlet at a bottom of the mixing column and an outlet at a top of the mixing column, the mixing column configured to receive a mixture of a powder and a compressed gas at the inlet. The sensor is disposed in the mixing column and configured to measure the concentration of the powder in the mixing column. The collection vessel has an inlet fluidly coupled to the outlet of the mixing column. The collection vessel is configured to collect the powder received from the mixing column.
