These instruments are designed to measure carbon dioxide in the range from 0 to 9,999 ppm. This range with good accuracy of meter allows users to conduct the most precise quantitative measurements of carbon dioxide in the space. The build-in temperature/humidity sensor also provides the cross-references for further analysis.
