The AirPhoton IN102Ex Extended Range Size Scanning Nephelometer has the same capabilities as the IN102 but expands the measurement size range to include PM1, allowing users to determine full aerosol particle size distribution. This is facilitated by the cyclone inlet and feedback flow control system and makes the IN102Ex uniquely valuable for advanced scientific research.

The IN102Ex’s small, compact design and protective case allow it to withstand a wide range of temperatures and humidity conditions in the field. It can measure different particle sizes in normal ambient conditions, as well as at high altitude or remote locations due to the high-speed fan which permits higher pressure intake.

AirPhoton integrating nephelometers are utilised by the international SPARTAN and NASA MAIA particulate air pollution initiatives, and are whitelisted for use in the European Aerosol, Clouds, and Trace Gases Research Infrastructure (ACTRIS). In SPARTAN stations, they are combined modularly with AirPhoton AeroExplorer Samplers which enables programmable sample collection in addition to real-time particle analysis provided by the nephelometer.
