Condensation nuclei counter with automatic ranging |
摘要 |
A condensation nuclei counter for measurement of the concentrations of Aitken particles in gases by measurement of light scattered in a cloud chamber by water droplets formed on the particles in successive samples of a gas wherein the counter provides for sequential high speed sampling of the photodetector output during the cloud chamber growth of the droplets of each gas sample tested as a way of measuring the rate of increase of total droplet cross-section and wherein the counter provides for automatic ranging for particle population coordinated with the timed sampling during particle growth.
