Description

Technical Field

[0001] The utility model relates to the technical field of indoor environment detection devices, in particular to an indoor environment pollutant concentration detection device. Background Art

[0002] Modern homes are usually renovated before people move in. As building decoration materials are used, the indoor air will be polluted by harmful substances such as formaldehyde released by the building materials. When the human body breathes air containing high concentrations of harmful gases such as formaldehyde for a long time, it will cause harm to the human body. Therefore, before moving into a newly renovated home, the indoor air is usually tested.
