|Manufacturer||MetAir, in co-operation with PSI|
|Name||Trace Gas Analyzer|
|Acronym||Trace Gas Analyzer|
|Measured parameter||Trace Gas concentrations|
|Operating mode||In situ|
no real restrictions, but, the instrument is more suitable for measurements in the boundary layer (mixed layer, with NO2-concentrations >2 ppb) than in background concentrations in the Free Troposphere.
28 VDC, 90 VA
presently only operational in MetAir's DIMO. Other similar instruments are in service at MeteoFrance, and in the DO-128 of TU-Braunschweig. Status of certification there is unknown.
The calibration is done by injecting NO2 from a permeation source (or from a 10 ppm cylinder) via a capillary in a variable air flow. The NO2 concentration can be referenced to O3 by using the Ox-channel. Therefore, NO2 losses in the system and other uncertainties are cancelled.
Yes, in principle. But, the user has to be skilled, trained, and has to perform the certification for his/her use.
|Could also fit on any aircraft having the following characteristics|
