Easy to use: CO2 measurement. The sensor module is highly precise, stable, and interference-proof. Carbon dioxide concentration can be displayed with high accuracy. Humidity display and three measurement modes. We recommend using it with a USB charger.

Real-time monitoring: The CO2 sensor has a built-in high-performance chip and uses monitoring technology to report ventilation needs. It records pollution data more accurately and is energy-efficient. The current generated during the electrochemical reaction is not limited by location or time, allowing for an accurate calculation of CO2 values and supporting 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 they can be seen at a glance. The screen brightness can be adjusted by pressing the left and right buttons on the power switch and adjusting the brightness according to the mode, making it a smart meter.

Compact design and versatility: It can be used as a desktop or wall-mounted unit. The CO2 concentration meter has a compact design, small size, light weight, is easy to carry, and has a new style. The CO2 meter is used not only in the home, but also in places where people gather, such as schools, hospitals, restaurants, shopping malls, savings banks, and places with poor ventilation, manufacturing facilities, luggage storage, greenhouses, etc.
