The Brechtel Model 1205 GCVI is the ideal virtual impactor tool for probing the detailed properties of actual cloud condensation nuclei (CCN) inside real clouds. The GCVI was developed for long-term, unattended deployments at mountain and other sites with accessible clouds so researchers could explore aerosol-cloud interactions with the ease of ground operation. Significant anti-icing experience from decade-long aircraft inlet development was applied to the GCVI to ensure the automated wind tunnel lid would open and close reliably under most sampling conditions. With on-line cloud, rain and snow detection, the built-in software will automatically turn your system on when cloud is detected and off when the clouds disappear.
