This machine is equipped with a carbon dioxide sensor and a temperature and humidity sensor, which can measure the carbon dioxide concentration in the air and the ambient temperature and humidity in real time. The measurement range of carbon dioxide concentration is 400-6000ppm. When the concentration is between 400-800, a green band is displayed. This means that the carbon dioxide concentration in the air is low and the air is in a normal state. Both the green and yellow bands are displayed between 800 and 1200, which means that the carbon dioxide concentration is higher. In this environment, it is harmful to the human body, showing green, yellow and orange stripes between 1200 and 1500ppm, indicating that the air is not good for the human body; if it exceeds 1500, the green, yellow, orange and red bands simultaneously show carbon dioxide concentration Severely exceeded. When it exceeds 5000ppm, it may cause suffocation or even death. You should open the windows immediately to ventilate

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
