The Alphasense Nitrogen Dioxide Electrochemical range of sensors, are available in the company's 'A' ,'B' and D series sizes, and are clearly blue colour coded. The NO2 sensors supplement the already established Toxic Gas Sensor ranges, which include Carbon Monoxide, Hydrogen Sulfide, Sulfur Dioxide, Nitric oxide and Chlorine. The 'A' series is also available as an oxygen sensor.
The Alphasense NO2-A/B/D Sensors provide OEM's with an alternative for use in a number of high volume applications. Strong signal levels combined with low zero current allows resolution to 50ppb (parts per billion) and an operating range of 20ppm (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 to transient relative humidity changes, compared to other available products. Physical robustness allows the sensors to be used 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 at the time of despatch so that full traceability is maintained.
