Harmful gas detector-Nitrogen dioxide, chemical formula NO2. It is brown-red toxic gas at high temperature. Toxic and irritating, it can react violently with many organic compounds. Nitrogen dioxide plays an important role in the formation of ozone. Man-made nitrogen dioxide mainly comes from the release of high-temperature combustion processes. Such as automobile exhaust and boiler exhaust.
Nitrogen dioxide is also one of the causes of acid rain, bringing various environmental effects, including: the impact on the competition and composition changes between wetland and terrestrial plant species, the reduction of atmospheric visibility, and the acidification and eutrophication of surface water ( The proliferation of algae, which are rich in nutrients such as nitrogen and phosphorus, leads to hypoxia), and the number of toxins harmful to fish and other aquatic organisms in the water increases.
Nitrogen dioxide electrochemical sensor is an instrument specially used to detect the NO2 content in the environment. Its main function is to monitor the concentration of NO2 gas and NO2 in the surrounding air at any time in an open environment. Once the NO2 concentration reaches a certain value, the instrument will sound, flash and vibrate triple alarms.
Functional characteristics of nitrogen dioxide electrochemical sensor:
Extend the startup time
Nitrogen dioxide electrochemical sensor instrument can detect in real time or periodically (in view of the small amount of gas to be detected). When it is not used for detection, the pump can be turned off to extend the start-up time.
The data recovery function can be fully recovered or selectively recovered, eliminating the worries caused by misoperation. It can automatically identify and prevent misoperation during concentration calibration, and avoid data defects caused by human factors.
The instrument and equipment can record calibration logs, maintenance logs and fault solutions, reminders of the expiration of sensor life, and reminders of the time for the next concentration calibration.
The nitrogen dioxide detector can automatically track the zero point, and long-term use is not affected by the zero point drift. The target three-level calibration ensures the linearity and accuracy of the measurement, while also being able to meet the national standards and the standards of the local metrology bureau.
The hazards of inhaling too much nitrogen dioxide:
Harmful gas detector-Health hazards: Inhalation of excessive nitrogen oxides mainly damages the respiratory tract. At the initial stage of inhalation, only the eyes and upper respiratory tract will have slight irritation, such as pharynx discomfort and dry cough. After an incubation period of more than ten hours, there will be delayed pulmonary edema, adult respiratory distress syndrome, chest tightness, cough, cough, and sputum foam. About two weeks after the pulmonary edema subsides, delayed obstructive bronchiolitis may appear.
Chronic effects: Mainly manifested as chronic respiratory inflammation and neurasthenia syndrome. Pulmonary fibrosis may occur in individual cases. May cause tooth erosion.
