you can buy or rent a meter that reads it from a boiler service enginner. they are not cheap though and need calibrating to get meaningfull results. very easy to comtaminate the sensor as well so be carefull where you poke it.

When I worked at ICI we used a hand held aspirator called a drager (pronounced drayger) the appropriate vial of chemical was placed in it and then air pulled into it by hand pumping. The level of NO/NO2 was then read on the vial where the chemical had changed colour.
If the Nitric acid plant had malfunctioned we had to check the NOX levels on the site.

I used to travel on business carrying a Drager kit to measure the quality of gas from ships exhausts. It was always fun going through customs with glass tubes full of crystals!

If there had been a cyclohexane spill the cooling water had to be checked for any signs of vapour. If I was on nightshift I had to climb the external steps on the cooling tower and go through a door onto a walkway that went to the opposite wall.
It was a bit scary, occasionally a piece of green algae would fall off the wall above and splat me on the side of the face. I was at ICI Wilton when a big cyclohexane spill caught fire and 3 workers were killed.

i was at a folk festival at redcar and the campsite was next to wilton. you could see the flames from the flare towers though the tent walls. the air was almost unbreathable. we used to go into the showers and stand behind a stream of running water in order to breathe. i had dreams of the whole lot exploding. think redcar has the highest death from lung diseases in the country.

Nox isn't measured on the MOT test equipment I don't think
