The 4-in-1 CO₂ Air Quality Monitor is a versatile device that simultaneously measures four key parameters: carbon dioxide levels, temperature, humidity, and time. By continuously monitoring CO₂ levels, it helps maintain healthy and comfortable indoor conditions. The measurement range covers 400–5000 ppm for CO₂, 0–50°C for temperature, and 0–99% RH for humidity. It works well in homes, offices, schools, warehouses, as well as in growing or production spaces.
Easy-to-read LED display
The model is equipped with a large LED screen that allows for easy reading of data even from a distance. All key parameters are displayed simultaneously on the screen. The built-in clock features an alarm function with the ability to set three independent alarms.
Air quality indicator and alarm
The device uses a five-level air quality rating scale based on CO₂ concentration:
When the level exceeds 1500 ppm, an audible alarm sounds to indicate that ventilation needs to be improved.
Automatic brightness adjustment
The light sensor automatically adjusts the screen backlight intensity, ensuring good visibility during the day and comfortable use at night.
Practical design and installation
The housing is designed for efficient air circulation—numerous ventilation openings support proper sensor operation and heat dissipation. The device can be placed on a flat surface or mounted on a wall, increasing its versatility.
