Product Description人Anti engineering air quality monitoring instrumentIt is a device used to monitor the air quality inside civil defense projects such as basements, air raid shelters, etc. It can monitor the concentration of various pollutants in the air, including but not limited to carbon dioxide, carbon monoxide, volatile organic compounds, formaldehyde, particulate matter, etc.
The air quality monitoring instrument for civil air defense engineering usually consists of sensors, controllers, and display screens. Sensors can detect the concentration of different pollutants and transmit the data to the display screen for display through the controller. Users can observe the data on the display screen to understand the air quality inside the civil air defense project.
In addition, the air quality monitoring instrument for civil air defense engineering can also automatically alarm or trigger alarm devices. When the concentration of a certain pollutant in the air exceeds the preset safety threshold, measures can be taken in a timely manner to improve air quality and protect people's health and safety.
Overall, the air quality monitoring device for civil air defense engineering is an important equipment that can help people monitor and control the internal air quality of civil air defense engineering, ensuring people's health and safety.
