Nitrogen Dioxide Sensors (NO2) Description：

Specification Summary

Nitrogen Dioxide (NO2) gets in the air primarily through emissions from cars, trucks, buses, power plants and factories as a by-product of the combustion process. Its presence in air contributes to the formation and modification of other air pollutants such as ozone, particulate matter and acid rain.

Exposure irritates airways and can aggravate respiratory diseases, particularly asthma, leading to symptoms such as coughing, wheezing or difficulty breathing. Longer term exposures to elevated concentrations of NO2 may contribute to the development of asthma and potentially increase susceptibility to other respiratory infections. People with asthma, as well as children and the elderly are generally at greater risk of the negative health effects of NO2.

At Alphasense our Nitrogen Oxide Sensors (NO2 Sensors) are manufactured to the highest quality standards, resulting in products which are both highly accurate and highly sensitive across both the air quality and gas safety markets.

Alphasense Nitrogen Dioxide Sensors (NO2 Sensors) are available in a wide range of formats and both PPM and PPB variants, making them suitable for use in variety of applications, from fixed and portable detection instruments to environmental monitoring systems and networks.

A: 20mm diameter, the industry standard size for portable gas detectors

B: 32mm diameter package, the best choice for fixed site applications

D: miniature, with proven long-term performance. Sensors for the next generation of portable gas detectors

Our range of nitrogen dioxide sensors provides OEMs with reliable sensors for use in a number of high volume applications. Strong signal levels combined with low zero current allows resolution to 50 parts per billion (ppb) and an operating range to 20ppm. The sensors are suitable for use in fixed installation sensing heads, portable safety instruments, urban air monitoring and stack gas analysers.

The NO2 sensors offer our electrolyte leak-free guarantee and reliable long-term detection performance. The leakproof housing is moulded with a colour coded top for ease of identification.
