What is a CO2 Sensor? | How does it work? - CALT Sensor

An NDIR CO 2 sensor has 4 important parts, the chamber, gas inlet and outlet valve, infrared(IR) lamp, and an IR detector. One end of the chamber has an IR lamp that produces IR rays within the absorption band of CO 2 molecules. At the opposite end of the chamber, an IR detector is fixed to measure the intensity of the emitted rays. The inlet ...

Carbon dioxide sensor - Wikipedia

NDIR sensors are spectroscopic sensors to detect CO 2 in a gaseous environment by its characteristic absorption. The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic ...

How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. 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. …

Infrared gas analyzer - Wikipedia

An infrared gas analyzer measures trace gases by determining the absorption of an emitted infrared light source through a certain air sample. Trace gases found in the Earth's atmosphere become excited under specific wavelengths found in the infrared range. The concept behind the technology can be understood as testing how much of the light is absorbed by the air.

Back to Basics: CO2 incubators - Thermo Fisher Scientific

There are two kinds of CO 2 gas sensors. The first is the T/C (thermal conductivity) sensor. Thermo Scientific incubators offer a T/C sensor and electronics that are very stable, accurate and economical. In fact, T/C sensors are our most popular method of CO 2 control. They are long-lasting, comparatively inexpensive and robust. An IR (infrared) sensor is preferred for some applications ...
