Draeger Tubes - Nitrogen Dioxide 2/cMeasuring Range: 2 - 100 ppm (10 Tests per Box)
Ammosorb is useless. It's really only useful if you live next to a swamp or abattoir.
You really need to positively ID the NOx, and quantify how much.
A Draegar tube like this will work.
You also need to purchase a hand pump that fits the tubes. You can probably find a cheaper used hand pump on ebay.
Google the Draegar manual and it will explain how to use the pump, how to do the measurement and how to convert the reading into a concentration.
