What is DFU 1000?

Explanation:
DFU 1000 refers to a device designed to gather air samples continuously. A continuous sampler pulls ambient air at a fixed flow rate and collects particles on a filter or other collection medium, so you get a time-based record of particulate levels rather than a single snapshot. This approach is common in environmental or occupational hygiene work where monitoring exposure to dust and aerosols over time is important. The other options describe equipment with different functions—manipulating field samples, monitoring weather variables, or providing navigation signals—so they don’t fit the purpose of collecting airborne particles.
