IN102

AirPhoton Size Scanning Integrating Nephelometer

The IN102 introduces a cyclone inlet to allow for sampling particles in a specific size range. We carefully monitor and adjust the instrument flow rate. In combination with the cyclone inlet, this allows us to measure particles separately at PM2.5 and PM10, the sizes most critical for air quality studies. This capability significantly enhances our precision and effectiveness in environmental monitoring and research applications.

Like the IN101 model it is small and compact and is enclosed in an environmentally protected case, ready for outdoor deployment in rugged conditions. Power requirements are 40W @ 120 VAC (60W Max) and input power options include: 110/240 VAC,50/60Hz with provided power supply, and regulated 12VDC from sampling station with provided power connector. Other powering options can be made available upon request such as operating from batteries or solar power. Optional heaters are available at the expense of additional power consumption.

  • Dimensions: 9″ x 10″ x 24” / 22.9 cm × 25.4 cm × 61.0 cm
  • Mass: 6.8 kg
  • Operating temperature: -30 to +45°C
  • Wavelengths: 450, 532, and 632 nm
  • Angular range: 7° to 90° ; 90° to 170°
  • Full scattering = forward + back scattering
  • Standard range: 0.0-3,000Mm⁻¹
  • Extended range: 20,000Mm⁻¹ (upon request)
  • Lower detectable limit: <0.15 Mm⁻¹ (at 60 sec AVG); < 0.06 Mm⁻¹ for Backscattering (60 sec AVG)
  • Time resolution: 15 sec standard – 1 sec minimum
  • Sensitivity: < 0.1 Mm⁻¹
  • Clean air reference option provides automatic zero for span calibration
  • Data Interfaces: 4GB SD card (possible up to 32GB), RS 485, and USB

The IN102 can provide forward and back scatter measurements, three wavelenghts, high Speed fan, feedback flow control system and multiple Size bins.

We suggest the IN102 for high precision measurements with various size cut-offs under all conditions for air quality and health and climate applications.
