Jun 11, 2020· CO2 concentration in fresh air is about 400 parts per million (ppm). But get a group of people packed in a closed indoor space, and CO2 concentration can rise quickly. Recent studies suggest that as levels increase above 1,000 ppm, decision-making and other cognitive abilities decline. Roya Maboudian studies the properties of nano-materials, including how their surfaces affect their …
Dec 07, 2011· The technique used to measure CO2 in handheld instrumentation is called non-dispersive infrared (NDIR) CO2 Instrumentation These handheld meters measure CO2 only and displays in units of parts per million (ppm). An NDIR sensor in the top end of the meter measures gas content by diffusion through sensing holes.
