Colorimetric NOx sensor based on a porous glass-based NO2 ...

Abstract A new type of chemical sensor for gaseous nitrogen oxides (NOx, the sum of NO and NO 2 ) has been fabricated by combining a porous glass-based NO 2 sensing chip with an oxidizing agent. In this device, NO is first oxidized to NO 2 over the oxidizer on a porous glass sheet (8 mm square, 1 mm thick) prepared by soaking in a sulfuric acid/potassium permanganate solution, after which the ...

Where to Mount CO & NO2 Sensors for Diesel Exhaust ...

For vehicle exhaust applications that include diesel exhaust, CO and NO 2 sensor combination gas detectors should be used to monitor the hazardous gas levels in the enclosed space. CO is about the same density as air and will readily disperse throughout an area where there may be some air movement and activity, remaining in the breathing zone (4-6 ft from the floor). NO 2 gas is heavier than ...
