CHECK THE CHART BELOW
to see which FLIR G-Series camera model can
visualize the listed gas, and at what theoretical
sensitivity (high/medium/low)

 Maybe (requires field testing)         
LLow sensitivity (<250 ppm × m)         
MMedium sensitivity (<150 ppm × m)         
HHigh sensitivity (<50 ppm × m)
