CO2 In a Classroom – Indoor Air Quality

In Austria, building legislations state that CO2 amounts in a classroom should definitely not exceed 1,400 ppm. Normal outdoor CO2 concentration is in the range of 250-400 ppm; between 400 and 1000 ppm can be found in enclosed spaces that have good air exchange (ppm means “parts per million” and measures the mass of a chemical). Upwards of 1000ppm, causes drowsiness, and beyond 2000 ppm ...

Indoor Air Quality - why does it matter and how to measure ...

2021-05-31· The importance of Co2 measurement . CO2 concentration is a key indicator of air quality. As people spend more time in their homes, and even more during the pandemic crisis, indoor CO2 concentrations are often 2 to 5 times higher than typical outdoor concentrations. The optimization of air quality in rooms is essential for healthier and more productive indoor living and working conditions.

Why Measure CO2? |

CO2 storage safety alarms protect customers, employees and emergency first-responders near stored carbon dioxide. A leak anywhere in a stored CO2 delivery system can quickly fill an enclosed area with potentially dangerous CO2 levels. That's why CO2 safety alarms are critical in breweries, wineries, beverage dispensing areas, restaurants and fast food establishments, dry ice storage ...

concentration (Co) of carbon dioxide seldom varies by more than 100 ppm from the nominal value.* Because of this and in lieu of installing an outdoor CO2 sensor, most designers use either a one-time reading of the outdoor CO2 concentration at the building site or a conservative value from historical readings. This simplifies control,
