Ammonia - NH3
This page presents information about ammonia (NH3) – also known as hydrogen nitride: characteristics, effects on health, detection tools & systems - ammonia detector - and proper respiratory protective equipment (gas mask or powered air purifying respirator with K gas filter).
Ammonia (NH3) properties
Ammonia (NH3) - or hydrogen nitride - is industrially synthetized from nitrogen (N) and hydrogen (H2) using a catalyst (Haber-Bosch process). This substance is a key element for producing fertilizers and is used in the cooling industry. When dissolved into water, ammonia is used to produce household products. it is also exploited in the textile industry and for many other applications.

Ammonia effects on health
Above all ammonia is toxic (even at low concentrations) and very irritating to the eyes and breathing tracts. It can be easily detectable through smell with its pungent and asphyxiating smell. This gas is also flammable and explosive between 15 and 28% volume. Explosive reactions can occur if ammonia meets other substances such as halogens, mercury, or acetaldehyde.

Ammonia detector (NH3)
Even if NH3 is detectable through smell, only an ammonia detector can accurately measure concentrations of this gas. Two ammonia detection methods are available: either in toxicity with a ppm measurement, or in explosive potential with LEL percentage measurement (combustible gas detector).
For calibration and gas testing of your fixed or portable gas detectors, ammonia calibration gas cylinders are available.
