Importance of ammonia gas detection

NH3 detector is a sensor that detects the concentration of ammonia gas and can alarm. When it comes to ammonia, most people may not be very familiar with it. But in fact, we are very easily exposed to ammonia in our daily lives. Ammonia is a colorless gas with a strong pungent odor. It is lighter than air. Long-term exposure to ammonia may cause harm to human health. In industry, ammonia is used as an important chemical raw material. It is widely used in the production of urea, soda ash, ammonium nitrogen fertilizer and nitric acid. Such as the production of chemical fertilizers, nitric acid, ammonium salts, soda ash, and the production of synthetic fibers, plastics, dyes, urea, etc. in the organic synthesis industry.

Atmospheric pollution by ammonia

With the rapid development of industrial economy, the ammonia emitted into the atmosphere by all walks of life has gradually increased. The impact of these rising levels of ammonia on the climate has also become increasingly significant. On the one hand, ammonia in the atmosphere will react with gaseous pollutants such as sulfur dioxide and nitrogen oxides to form secondary aerosol particles that absorb and scatter light, reducing the visibility of the atmosphere. On the other hand, ammonia emitted into the atmosphere affects the temperature of the atmosphere as a greenhouse gas.

Types of ammonia sensors

NH3 detector is divided into fixed type and portable type. The portable ammonia alarm is easy to carry and can be turned on at any time to detect the concentration of ammonia gas at any time. The fixed ammonia gas alarm is composed of two parts: a gas detector and a gas controller. The gas detector is installed at the gas concentration detection site for real-time detection within 24 hours. The electrochemical ammonia gas sensor is used to detect the concentration of ammonia gas. The gas alarm controller is installed in a place where people are present and easy to observe, such as the duty room. Receive the ammonia concentration detected by the gas detector. And realize the concentration display and the sound and light alarm function after exceeding the standard. Link external equipment (solenoid valve, exhaust fan, etc.).
