RAE Systems Organic Vapor Zeroing Kit 002-3008-000
Charcoal filter attaches to the inlet probe of PIDs (photoionization detectors) to remove background VOCs (volatile organic compounds), allowing the instrument to reference a zero, or near zero, air sample. Used during the "Fresh Air Cal" procedure. The charcoal filter canister has a check box so that the user can mark off a box each time the filter has been used. The charcoal filter should be replaced after 4 calibrations.
