Electrochemical Sensors for CO/NOx Detection in Automotive ...

A sensor prototype based on the thick film design was then developed and tested. All the experimental results prove that the sensor can be successfully used for selective detection of CO and NOx. The selectivity results from an appropriate choice of the working temperature of the sensing element. At low temperatures (300 to 400°C) NO2 can be selectively detected in the presence of CO; the ...

Chinese CO Meter – The Sensor Cell – Experimental Engineering

09/02/2016· As the CO meter I bought on eBay didn’t register anything whatsoever, I decided I’d hack the sensor itself apart to make sure it wasn’t just an empty steel can. It turns out that it’s not just an empty can, but there are some reasons why the thing doesn’t work 😉 . Cell Disassembled. The cell was crimped together under the yellow shrinkwrap, but that’s nothing my aviation snips ...
