New range of ionic ammonia sensors Envirotech Online

18/06/2020· However, one of the main downfalls of current ammonia gas sensors is that they don’t really fit the bill, especially for refrigeration plants. Existing electrochemical sensors are consumed by ammonia as they are monitoring. This means if you have a background level in a plant room, then your sensor life will be drastically reduced. This also means, your sensor could become fully consumed …
