Industrial Fixed Nitrogen Dioxide (NO2) Gas Detector

Gas Detection Q&A - For Your Safety Environments

Built-in advanced gas detector sensor and sound & light alarm to ensure precise and safe gas detection in hazardous applications.

Q: How much NO2 is toxic?

A: The toxicity of Nitrogen Dioxide (NO2) varies depending on the concentration and duration of exposure. Short-term exposure to high concentrations of NO2 can be harmful. Inhaling NO2 at levels above 100 parts per million (ppm) for even a few minutes can lead to respiratory distress, coughing, and irritation of the throat and lungs. Prolonged exposure to lower concentrations, such as 5-10 ppm over several hours, can also cause respiratory symptoms in sensitive individuals.

Long-term exposure to Nitrogen Dioxide at levels typically found in outdoor air (usually below 0.1 ppm) can lead to chronic respiratory problems, worsen pre-existing lung conditions like asthma, and increase the risk of respiratory infections. Vulnerable populations, such as children, the elderly, and individuals with pre-existing lung diseases, are more susceptible to NO2's harmful effects. It's essential to monitor NO2 with gas detectors, especially in urban areas with high traffic and industrial activity, to minimize health risks.
