Nitric Oxide Gas Sensors

At room temperature, Nitric Oxide (NO) is a colourless, non-flammable and toxic with an irritating odor. Nitric Oxide sensors is extremely toxic by inhalation, and symptoms of over-exposure may not become apparent for up to 72 hours. In the presence of air, Nitric Oxide forms brown fumes of nitrogen dioxide and is extremely reactive and a strong oxidizing agent.

Alphasense Nitric Oxide Sensors (NO Sensors) are available in a wide range of formats, making them suitable for use in fixed and portable detection instruments as well as other instruments and systems where monitoring of NO is required.

Alphasense NO Sensors

Alphasense Nitric Oxide Sensors (NO 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 designed for the next generation of portable gas detectors.

The NO range 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 200 parts per billion (ppb) whilst giving linear outputs to as high as 250ppm. The sensors are suitable for inclusion in fixed installation sensing heads, portable safety instruments, urban air monitoring and stack gas analysers.

Alphasense NO sensors provide a significant improvement in stability of response to transient relative humidity changes.

The NO 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.
