we cannot measure it with our eyes. Right now, we need an air tester to help monitor the air quality.

Feature:
1: Widely used and practical, used for epidemic prevention and control to detect the concentration of co2 in the population, so as to control the number of people and avoid the risk of cross-infection.
2: This CO2 detector can accurately and quickly test CO2 levels indoors to protect your health. Also, provides real-time monitoring of indoor temperature and humidity.
3: Using infrared technology, high measurement accuracy, fast response, resolution up to 1ppm, can accurately detect CO2 in the air, the measurement range up to 400-5000ppm.
4: This indoor air carbon dioxide meter has 4-color LED indicators as an air quality warning. Different color indicators will flash according to CO2 content, which makes air quality more intuitive.
5: 1200mAh rechargeable battery provides 240-360 minutes of standby time and can be recharged via Type-C charging port.
