Ammonia Gas Detectors (NH3 Detectors)

NH3 Ammonium hydroxide, also known as aqueous ammonia, is a common solvent used in cleaning products and can be an ingredient in food products and fertilizers. Anhydrous ammonia (NH3) is the pure gas or compressed liquid form of ammonia that contains no water. It is used in the manufacturing of fertilizers, explosives, agricultural applications, cleaning fluids and in certain pharmaceuticals. Food and beverage companies use many tons of ammonia for refrigeration, flash freezing, and bulk storage, all running the risk of gas releases. Industrial Scientific’s personal single-gas detector GasBadge® Pro, or multi-gas detectors, including the Ventis® Pro, and the MX6 iBrid®, as well as the Radius® BZ1 Area Monitor reliably detect low ppm ammonia within the specified range.

Ammonia is a widely used chemical that can be found in a variety of common industrial environments. It is 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 as concentrations increase.
