Use: | Collection of VOCs from ambient air. |
Description:
A control device is used to maintain a constant flow of air into: (1) a canister, or (2) a filter over the desired sample period. More advanced equipment may utilize a sensor to identify when wind direction is coming from the suspected area of contamination.
