Ammonia (NH3) sensor module
Accurate air quality sensor for PPB level NH3 monitoring
The Ammonia sensor module can accurately measure low concentrations of NH3 at the ppb level in the ambient air. The sensor module design is capable to monitor the ammonia emissions from point sources on a real-time basis.
The advanced support electronics of this air quality sensor makes it compact and reliable. The low noise electronics allows stable and accurate detection of ammonia even at very low concentrations in the atmosphere.
The ammonia sensor module works on the electrochemical principle. Electrochemical sensors are very sensitive to the presence of NH3 and also provide a stable response to transient relative humidity changes. Hence, this makes it an ideal choice for indicative real-time air quality monitoring for outdoor applications.
Standard calibration gases and tools are used to calibrate the NH3 sensor. The calibration is in accordance with the USEPA (40 CFR Part 53) and EU (2008/50/EC) defined for equivalent method instruments.
Odour Monitoring Systems like Odosense Smart and Odosense Pro use the NH3 sensor module. Therefore, this module is ideal for applications like sewage treatment plants, effluent treatment plants, industries, landfills and solid waste management.
