Air quality is an important factor affecting our health in our daily lives. Especially in indoor environments, the content of formaldehyde and other harmful gases directly affects our quality of life. Many people are concerned about excessive formaldehyde levels after renovating a new house or purchasing a new car. At this point, a cost-effective indoor air quality monitoring device becomes particularly important. It can help us monitor the levels of harmful gases in the air in real time, allowing us to have a better understanding and peace of mind about our living environment.
The Osen indoor environmental air quality monitor monitors real-time indoor air pollution indices such as PM2.5, PM10, noise, temperature and humidity, carbon dioxide, ozone, carbon monoxide, formaldehyde, etc. It has been applied in homes, gyms, commercial centers, shopping malls, smart classrooms, offices, hospitals, schools, apartments, villas, residences, airports, subway stations, stations, restaurants, hotels, guesthouses, postpartum centers, nursing homes, cinemas, museums, libraries, etc.
