anyone know if you can use a heated o2 sensor to find the % o2 content from ~20% to 95%?
or are they only valid for low concentration exhaust?
got a cheap o2 concentrator and want to see the % output ( it doesn't use a o2 sensor )

Afaik car sensors won't work at that oxygen range.
If you're ok with tedious and somewhat inaccurate off-line measurement, you could just burn the oxygen away from a known volume of gas. A classic chemistry experiment uses steel wool, but sulfur works too.
Car o2 sensors need to be hot as fuck.
Biomed here. We use this guy to test the output of our O2 concentrators. It's basically just a fuel cell with a screen but it's nice because you can calibrate it with room air.
Or just google "oxygen analyzer" there are a ton of options.
