Latest Nitrogen Dioxide Sensor - Low PPB Detection and Low Cross Sensitivity

Alphasense Limited (UK) launched their latest version Nitrogen Dioxide (NO2) 4-electrode sensor, the NO2-B43F. This addition to the Alphasense electrochemical range of sensors is available in both Alphasense’s "A" 20mm and "B" 32mm Series versions. This NO2 sensor supplements the already extensive and well established Toxic gas sensor ranges.

The new Nitrogen Dioxide sensor provides Original Equipment Manufacturers with an alternative to other offerings for use in a number of applications. Strong signal levels combined with low zero current and the 4th electrode allows resolution to 10 parts per billion. The sensors are suitable for inclusion in fixed installation sensing heads, portable safety instruments or stack gas analysers.

The sensors incorporate innovative catalyst technology and special filters for Ozone, NO etc., which reduces the effects of a number of common cross interference gases whilst ensuring batch to batch consistency and stable output. Physical robustness allows use of the sensors in the most demanding environments.

As with all other Alphasense sensors the use of stabilisation racks to continuously monitor every sensor during initial conditioning ensures that only sensors operating within specification are passed to the companies unique ATAV (Alphasense Test and Validation) system. The key operating characteristics for every sensor are recorded against the sensor serial number which is bar coded onto the sensor. This data can be released to purchasers at the time of despatch so that full traceability is maintained.

Alphasense continues to invest in new Sensor Technology and to pursue its philosophy as a "Centre of Excellence" for the development and supply of innovative gas sensors.
