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 times. It captures pollution data more accurately and is weak. The current generated during the electrochemical reaction is not limited by location or time, allowing for accurate calculation of CO2 assessment and supporting daily infection control and a comfortable environment.

Easy-to-read LCD display: The CO2 concentration meter has a large LCD display with good visibility. It shows CO2 concentration, temperature, and humidity in large letters. They are also color-coded 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 position, making it a smart meter.

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