Detection of NO2 in ambient air
InAir-NO2 is an optochemical sensor based on Insplorions patented Nanoplasmonic Sensing technology (NPS). The active sensor element is a semi-transparent glass chip covered with plasmonic nanostructures and a functional coating. Readout is accomplished using light-emitting diodes and photosensitive detectors to measure the interaction between the sensor element and NO2 gas molecules. Concentrations in the range of a few mg/m3 (ppb) can be detected.
InAir-NO2 is a miniaturized high performance sensor that enables cost effective detection and measurement of NO2 levels in ambient air.
The InAir-NO2 is available for both diffusive measurements and with connections for pumped air flow. Both configurations come with a precalibrated sensor element.
The sensor can be calibrated for optimal performance at a certain temperature and humidity. The drift and temperature compensated signal is presented in ppb by volume [1 ppb NO2 = 1.88 mg/m3]. For purposeful and adaptive calibration at a certain location of interest the raw uncalibrated signal is also presented.
