How to Measure Carbon Dioxide - Vaisala

Operation Principle of Infrared Sensors Carbon dioxide and other gases consisting of two or more dissimilar atoms absorb infrared (IR) radiation in a characteristic, unique manner. Such gases are detectable using IR techniques. Water vapor, methane, carbon dioxide, and carbon monoxide are examples of gases that can be measured with an IR sensor. Their characteristic absorption bands …

Telaire Guidelines for CO2 Sensor Selection

carbon dioxide (CO 2), and total volatile organic compounds (TVOC’s) in the indoor environment. In this application note, we will focus on measuring the amount of CO 2 in the air. In 1989, Telaire started a project to develop a low cost non-dispersive infrared (NDIR) sensor to measure CO 2 concentration in air. Telaire introduced the first maintenance free CO 2 sensor in 1992, and has since ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

IR radiation with µm is not absorbed by either CO2 or other common gases in the atmosphere and is transmitted without loss to the detector. Therefore, it is well suited as reference with no absorption. IR radiation with µm wavelength is only absorbed by CO2 molecules and by no other gases in the atmosphere. This means, that the degree of radiation reduction on that channel depends ...

Infrared Carbon Dioxide Sensors -

Calibration of infrared carbon dioxide sensors. The sensor requires a two-point calibration. First, the carbon dioxide sensor must be zeroed. This is performed by flowing a gas without carbon dioxide through the analyzer and adjusting the zero on the analyzer. Second, the span needs to be adjusted. A span gas containing an amount of carbon dioxide close to the concentration of carbon dioxide ...

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes.

How does an NDIR CO2 Sensor Work? |

An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR radiation produced by the lamp is very close to the absorption band of CO2.

Manual amc310 infrared CO2 sensor-transmitter

quick but approximate calibration verification can be done by supplying the unit with outside air and letting the reading stabilize. CO2 concentrations in outside air are typically between 350 and 450 ppm. A more accurate calibration check requires the use of calibration gas of known concentration; a 1/8" flexible tube, regulator and calibration gas cylinder are needed. To verify the Model 310's calibration, …
