Electrochemical nitrogen monoxide (NO) sensor
Alphasense

The Alphasense Electrochemical range of Nitric Oxide sensors are available in both the companies 'A' and 'B' series sizes and are colour coded in light blue moulded tops. The NO sensors supplement the already established Toxic Gas Sensor ranges that include Carbon Monixide, Hydrogen Sulfide, Sulfur Dioxide and Chlorine. The 'A' series is also available as an oxygen sensor.

The alphasense NO-A/B provides OEM's with a good, reliable sensor for use in a number of high volume applications. Strong signal levels combined with low zero current allows resolution to 200ppb (parts per billion) whilst giving linear outputs to as high as 250ppm (parts per million). The sensors are suitable for inclusion in fixed installation sensing heads, portable safety instruments and stack gas analysers.

The sensors incorporate innovative catalyst technology, which reduces the effects of a number of common cross interference gases whilst ensuring batch-to-batch consistency and stable output. These sensors provide a significant improvement in stability of response with respect transient relative humidity changes. These sensors allow OEM's to design instrumnts that provide trouble free monitoring of the reduced allowable maximum exposure limit of 1.0ppm for Nitric Oxide. Physical robustness allows the sensors to be used in the most demanding environments.
