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 (46 ft from the floor).
