👉 A carbon meter, also known as a carbon-dioxide (CO2) meter or a carbon dioxide concentration analyzer, is a device used to measure the amount of carbon dioxide gas in an environment. It works by measuring the rate at which the atmosphere cools due to the absorption of solar radiation. The CO2 concentration is then converted into a readable value using a calibrated instrument that measures the temperature of the atmosphere and converts it into a readable value, such as the density of the air or pressure.
