Alphasense nitrogen dioxide sensors
Alphasense nitrogen dioxide sensorsKeywords: Gas sensors, Nitrogen
Alphasense Limited has launched its new range of nitrogen dioxide (NO2) sensors.
These additions to the Alphasense electrochemical range of sensors are available in both the company's "A" and "B" Series sizes and are clearly colour coded in blue moulded bodies. The NO2 sensors supplement the already established toxic gas sensor ranges which include carbon monoxide, hydrogen sulphide and sulphur dioxide. The "A" series is also available as an oxygen sensor (see Plate 2).
The new nitrogen dioxide sensors provide original equipment manufacturers with an alternative to other offerings for use in a number of high volume applications. Strong signal levels combined with low zero current allow resolution to 50 parts per billion and an operating range of 20 parts per million. The sensors are suitable for inclusion in fixed installation sensing heads, portable safety instruments or stack gas analysers.
The sensors incorporate innovative catalyst technology which reduces the effects of a number of common cross interference gases while 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 company's 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.
