CO100 allows you to control the air quality in rooms where CO 2 -Level can be a bit of a hassle. Too high a value negatively affects health, ability to concentrate and our well-being. The CO2 value should be monitored in all rooms where many people are present for a long period of time. The display can read the value of CO2, air temperature and humidity as well as the time and date at the same time. For a simple analysis of the CO2 value, an additional index symbol is displayed: Good (0 - 800 ppm), Normal (800 - 1200 ppm), Poor (>1200 ppm). If the set alarm value is exceeded, an alarm signal sounds.
