Easy to use: CO2 measurement. The sensor module is high-precision, stable and resistant to interference. The carbon dioxide concentration can be displayed accurately. Humidity display and three measurement modes. We recommend using it with a USB charger.

Real-time detection: The CO2 sensor has a built-in high-performance chip and uses monitoring technology to report ventilation intervals. It detects pollution data more accurately and is weak. The current generated during the electrochemical reaction is not limited by location or time, which enables accurate calculation of CO2 assessment and supports daily infection control and a comfortable environment.

Easy-to-read LCD screen: The CO2 concentration meter has a large LCD screen with good visibility. It displays CO2 concentration, temperature and humidity in large letters. They are also color-coded so you can see it at a glance. The screen brightness can be adjusted by pressing the left and right buttons on the power button and adjusting the brightness according to the position, making it a smart meter.

Compact design and versatility: It can be used as a table/wall-mounted unit. The CO2 concentration meter has a compact design, is small, light, easy to carry and has a new design. The CO2 meter is used not only in the home, but also in places where people gather, such as schools, hospitals, restaurants, shopping centers, savings banks and poorly ventilated places, production facilities, luggage storage, greenhouses, etc.
