Description

Automatic online monitoring device for ammonia escape

Technical Field

The utility model relates to the technical field of ammonia detection, in particular to an automatic online monitoring device for ammonia escape.

Background

Ammonia is a compound of nitrogen and hydrogen, has a molecular formula of NH3, is a colorless gas at normal temperature, and has strong pungent odor. Is very easy to dissolve in water, and 1 volume of water can dissolve 700 times volume of ammonia at normal temperature and normal pressure, and the water solution is called ammonia water.

The ammonia gas is colorless, so that the ammonia gas is difficult to detect after escaping, and the ammonia gas can be judged only after people smell pungent smell, so that the detection effect on the ammonia gas is poor.
