  • Air sampler with closed loop flow control system
    Patent number: 10001115
    Abstract: A battery powered, personal air sampler is described which uses a closed loop control circuit to adjust the power that is delivered to an internal pump such that a stable and accurate flow rate is maintained independent of changes in inlet pressure due to filter loading. Furthermore, the described personal air sampler provides improved efficiency to the entire electronic and flow pumping system which, in turn functions to optimize the available battery run time of the device.
