CO₂ meter

The Dewofire CO2 meter with battery is the best price-quality option among CO2 monitors.
The backup battery lasts up to 10 hours and allows you to easily move the device around. The extra-large LCD screen provides all essential information at a glance to accurately assess air quality: the current CO2 level in PPM (including an adjustable history), humidity, and temperature. Ideal for use at home, in offices, schools, care facilities, and any other locations where air quality is crucial.

The normal amount of CO2 in the air ranges between 600 and 800 particles per million (PPM). Higher concentrations can lead to concentration problems, headaches, muscle pain, fatigue, and other complaints. The Dewofire CO2 meter emits a clearly audible alarm when the threshold value (which you can set yourself) is exceeded. In addition, an LED indicator provides an immediate overview of the current air quality: green (all good), orange (improvement possible), or red (unhealthily high).

The CO2 monitor is equipped with a precise NDIR CO2 sensor, capable of accurately measuring up to 5,000 PPM, and features automatic calibration.
