NO-B4 Nitric Oxide Sensor (NO Sensor) Description
Alphasense Nitric Oxide gas sensors operate using proven fuel cell technology.
NO-B4 Nitric Oxide Sensor size:
32mm diameter package, the best choice for fixed site applications
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.
