Nephelometers
[General]
AirPhoton 3-wavelength Integrating Nephelometers measure the light scattered
by particulate matter, over the angular range 7° to 170°.
Employing an innovative design, the forward and backward scattering measurements
are made completely independently. LED technology is employed to make these
measurements at 450nm, 532nm, and 632nm, and to a sensitivity < 10^-7m^-1.
Internal sensors measure and log temperature, relative humidity and pressure.
Small and compact, our integrating Nephelometers are robust and ready for
outdoor deployment in rugged conditions. Power requirements are 15W@120VAC.
Input power options include: 110/220 VAC, 50/60Hz with provided power supply,
and regulated 12VDC from sampling station with provided power connector.
Other power 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 consumptions. data from our integrating Nephelometer
are saved in a removable SD memory card and can be linked to an external
computer via RS485 using accessories available from AirPhoton.
Our nephelometers are desined for easy integration with our AeroExplorer
Filter Sampling Stations to allow for combined real time and retrospective
particle analysis.

Small and compact, the IN101 3-wavelength Integrating Nephelometer is enclosed in an environmentally protected case, ready for outdoor deployment in rugged conditions. Power requirements are 40W @ 120 VC (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.
Data from the AirPhoton IN101 Integrating Nephelometer is saved in a removable SD memory card and can be linked to an external computer via RS485 or wirelessly via Bluetooth.
AirPhoton collected data with the IN101 nephelometer while exhibiting at the AGU meeting at the Moscone Center in San Francisco in December 2014. You can see the data here: Moscone Nephelometer. Additional data showing some very interesting results collected at night at the Moscone Center can be found on the AirPhoton Facebook page along with an explanation and the story behind the data.
