Features:
When there is no indoor ventilation in winter, you can accurately and quickly test the indoor carbon dioxide for your health by using our carbon dioxide measuring equipment. At the same time, our detector can monitor the indoor TVOC (air pollutant), formaldehyde, temperature and humidity in real time. It is the best choice for your healthy life!
With the large LCD screen display and 24 hours real time monitoring function, you can see the data more clearly at any time, give you a better using experience.
In alert mode, the screen changes color as the air quality situation changes, alerting the user to notice the environment.
The temperature unit can be switched between Celcius (?) and Fahrenheit (?), you can choose the one you like.
Perfect to be used to monitor air quality in schools, office buildings, greenhouses, factories, hotels, hospitals, laboratory and anywhere that high levels of carbon dioxide and formaldehyde are generated.
