Gas Sensors Ammonia -

Ammonia can be measured in air or in liquid (dissolved) using a variety of methods. The most common method is using Electrochemical Gas Sensors, which is what all of our Ammonia products use. Ammonia is normally measured in parts per million (ppm) for human safety uses but can also be measured in percent by weight for commercial production and storage applications. All of our ammonia …

Understanding Ammonia Sensors and their Applications

Ammonia sensor capabilities and limitations Almost anyone who has used ammonia sensors in refrigerated areas is aware of the limitations of the sensors. The environment is just plain tough on sensors. Temperatures can range from – 40° (in some flash freezing operations) to + 40° C (during defrost periods). Strong jets of water, steam and detergents used during wash-down procedures can ...

Ammonia sensors and their applications—a review

3. Application areas of ammonia sensors There are many ways to detect ammonia. High concentra-tions are easy to detect because the gas has a very penetrat-ing odour. With respect to other odorous gasses, the human nose is very sensitive to ammonia. To quantify the ammonia concentration or determine lower concentrations of ammo-nia, the human nose fails. However, in many occasions, the
