F&J Model DF-1L-BL-8 is a lightweight, small footprint, DC voltage powered air sampling system operable from (1) on-board 4500 mAH NiMH batteries, (2) line power, or (3) automobile cigarette lighter socket.
The DF-1L-BL-8 is well suited for low flow rate air sampling activities where users do not know whether line power will be available. Typical operating time from on-board batteries is greater than 8 hours when utilizing FP47M glass fiber filter paper.
