The issue of malodor has long been one of the key factors affecting environmental quality and people's lives. The malodor OU value is a critical indicator for measuring malodor intensity, reflecting people's subjective perception of odor. The higher the OU value, the more severe the malodor, and the greater its impact on human comfort and mental health. Prolonged exposure to environments with high OU values may cause symptoms such as irritability, anxiety, and insomnia.

Therefore, monitoring malodor OU values is essential.

The FT-EC03A Odor Gas Online Monitoring System can accurately and rapidly measure malodor OU values, as well as concentrations of multiple malodorous gases such as ammonia and hydrogen sulfide, enabling real-time and continuous monitoring of malodors in polluted areas.

Ammonia is a common malodorous gas that is also harmful to humans. It causes corrosion and irritation to skin tissues, absorbs moisture from the skin, denatures tissue proteins, saponifies fats, and damages cell membrane structures. When the concentration of ammonia in the air is excessively high, it severely irritates and corrodes the respiratory tract, leading to respiratory diseases. Short-term inhalation of large amounts of ammonia can cause symptoms such as tearing, sore throat, hoarseness, coughing, blood in sputum, chest tightness, and difficulty breathing. In severe cases, pulmonary edema, adult respiratory distress syndrome may occur, and cardiac arrest and respiratory failure may even result from excessively high ammonia concentrations in the blood, endangering life. Long-term exposure to ammonia may cause skin pigmentation or finger ulcers in some individuals, and it can also damage the nervous system, leading to headaches, dizziness, and memory loss.

Hydrogen sulfide is another highly hazardous malodorous gas with a strong rotten egg smell. Even low concentrations of hydrogen sulfide affect the eyes, respiratory system, and central nervous system. Moreover, it can paralyze the olfactory nerves, making it difficult for people to judge its concentration by smell, thereby increasing the risk of poisoning. When hydrogen sulfide reaches certain concentrations, it poses a severe threat to life, such as inhibiting the central nervous system and causing respiratory paralysis and death. Long-term low-concentration exposure to hydrogen sulfide can cause conjunctivitis and corneal damage, affecting vision. At the same time, hydrogen sulfide irritates the respiratory tract, causing respiratory inflammation, pulmonary edema, and other diseases, and it also damages the myocardium, potentially leading to symptoms such as palpitations and chest tightness.

Once the pollutant concentrations exceed the standard, the FT-EC03A immediately issues an alarm, allowing relevant personnel to promptly take measures to address the pollution problem.
