The challenges with electrochemical NO2 sensors in outdoor ...

2018-07-23· Some NO 2 sensors include an internal filter designed to remove O 3 and other oxidizing gas interferents before they reach the sensing electrode. Thus, the sensor is not affected by the presence of O 3. While inclusion of a filter (such as M n O 2) is frequently able to increase specificity, the filters have a finite lifespan because they lose their effectiveness before the operating life of ...

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 ...
