Ammonia (NH₃) is a colourless gas made up of nitrogen and hydrogen. It has a strong, sharp smell that most people recognise from cleaning products. It is lighter than air and highly soluble in water, where it forms an alkaline solution that can be corrosive.

Ammonia is produced through the breakdown of organic matter and is found in soil. Industrially, it is one of the most widely manufactured chemicals in the world. It is commonly present in refrigeration systems and beverage production.

Ammonia is primarily used in the production of fertilisers, which support global food production. It is used as a refrigerant gas in large cold storage and food processing facilities because of its efficiency and low environmental impact compared to some synthetic refrigerants.

Rockall Safety offer a range of gas detectors to monitor ammonia levels such as the BW Solo Single Gas Detector and the Blackline G8 Multi-Gas Pumped Detector.
