IN102Ex (extended range) Size Scanning Nephelometer
The IN102Ex Size Scanning Nephelometer extends the capabilities of our IN102 nephelometer aerosol to sample in the range from PM1 to PM10. The additional range of the measurements allows us to derive the full particle size distribution. We use the same feedback flow control system as described above for the IN102. See the video at the top of this page for a discussion of its capabilities and a demonstration of its ability to derive a size distribution.
