[0002] Indoor formaldehyde detection instruments are usually electronic devices that have the function of detecting the formaldehyde concentration in indoor air. They measure the formaldehyde content in the air through sensors or chemical reactions, and display the results on the screen of the instrument or provide them to the user through other means. The role of these detection instruments is to help people understand the level of formaldehyde in indoor air so that they can take necessary measures to improve indoor air quality and protect health. Therefore, they play an important role in homes, offices, factories and other places to provide a safe and healthy living environment.

[0003] Indoor formaldehyde detection instruments are usually composed of detection terminals, sensors, display screens, power supplies and control panels, which together form indoor formaldehyde detection instruments, so that they can accurately and reliably detect the formaldehyde content in indoor air, helping users ensure the health and safety of their living and working environments.
