Ammonia (NH3) Gas Detectors

Ammonium hydroxide, also known as aqueous ammonia, is a common solvent in cleaning products and ingredient in food products and fertilizers. Anhydrous ammonia (NH3) is the pure gas or compressed liquid form of ammonia that contains no water. This form is used in fertilizers, explosives, agriculture, cleaning fluids, and certain pharmaceuticals. Food and beverage companies also use many tons of ammonia for refrigeration, flash freezing, and bulk storage, all running the risk of gas releases.

Characteristics of Ammonia (NH3)

Ammonia can be found in a variety of common industrial environments. It's a colorless gas with a pungent suffocating odor. Ammonia is characterized as a flammable although it is very difficult to ignite. When exposed to heat, an ammonia solution will decompose to form ammonia gas and oxides of nitrogen (NOx). Ammonia is an irritant and will become extremely irritating to anyone exposed to it as concentrations increase.

Effects of Various NH3 Levels

Ammonia Level in PPM
Resulting Conditions on Humans
Minor irritation of the eyes and respiratory tract.
Permissible Exposure Limit (OSHA).
Swelling of the eyelids, conjunctivitis, vomiting, irritation of the throat.
Concentrations are dangerously high, irritation becomes more intense. Death can result from highly concentrated, prolonged exposure.
