The Source of Ammonia and Application of Ammonia Sensors

Gaseous ammonia origin on the earth,the harm of ammonia to the human body,the importance of determination to ammonia and the application domain of gaseous ammonia sensors were introduced. Apart from its natural origin,there were many sources of ammonia,like the chemical industry or intensive life-stock. The investigation indicated the gaseous ammonia sensors had been used in many domains now. The examination limits and the response time of the ammonia sensors in the different domains,the temperature which the ammonia sensors equipment may withstand were discussed.
