CO2 Display PCE-AC 4000
CO2 display to determine CO 2 concentration, humidity and temperature indoors / 
CO 2 measurement range of 0 ... 9,999 ppm / temperature measurement range -40 ... +85 °C / large, clearly readible, three-colored LED display / simultaneous display of all parameters

The CO2 display PCE-AC 4000 is an ideal device to monitor the air quality indoors. The CO2 display PCE-AC 4000 is easy to navigate and measures in addition to the CO2 concentration also the  temperature and relative humidity. The CO2 display provides important information about the air condition and quality in classrooms, offices, conference rooms, auditoriums, hospitals, restaurants and any other public or private space. Ideal conditions in inner spaces can be very crucial to assure effective working and learning. Even with a CO2 level above 1500 ppm the first symptoms of tiredness begin to occur. Thus the CO2 display shows the air quality at any time.
