CO2 – Measurement and Monitoring of Carbon Dioxide in Rooms

CO2 – Measurement and Monitoring of Carbon Dioxide in Rooms. Room air monitoring is usually limited to humidity and temperature. Especially in times of a pandemic, measuring and monitoring CO2 is also very important. Correct ventilation in crowded rooms, will significantly reduce the risk of infections including the coronavirus.

Basic Principle of NDIR Gas Detection Heimann Sensor

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the BeerLambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
