The challenges with electrochemical NO2 …

23-07-2018· Interfering gases and cross-sensitivity. In a perfect world, an electrochemical sensor would only respond to the gas it is targeted to monitor. A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses …

Nitrogen gas detector, N2 nitrogen CAS 7727-37-9 …

As nitrogen is colorless and odorless, the organism can absolutely not detect this gas. Only a nitrogen gas detector (oxygen meter) can accurately measure nitrogen concentrations (or rather oxygen rate in the air). Thus an oxygen detection system (or oxygen depletion sensor) performing measurements in percentage of the volume should be selected.
