Product Q&A

Q:What is NO2?

NO2 is Nitrogen Dioxide, a brown-red, highly reactive gaseous substance. It plays an important role in the formation of ozone and mainly comes from high-temperature combustion processes like vehicle exhaust and power plants.

Q:Where to use the Nitrogen Dioxide Sensor?

It is used in underground coal mines (goaf, mining face, return air tunnel) for safety monitoring. It is also widely used in chemical, meteorological, water disinfection, food processing, medical hygiene, and smart home applications.

Q:What is a Nitrogen Dioxide Sensor?

A Nitrogen Dioxide Sensor is an instrument used to detect the concentration of Nitrogen Dioxide and usually has an alarm function.

Q:What is the working principle of the NO2 Sensor?

The sensor uses the electrochemical working principle. It works based on the diffusion of NO2 gas into the sensor and converts the measured NO2 concentration into an electrical signal output.

Q:How long do NO2 sensors last?

Under normal circumstances, our NO2 Sensor can be used for 5 years.
