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. …

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 ...

Infrared Sensor Technology and its Impact on Measurement ...

Most infrared CO 2 sensors use a miniature incandescent light bulb as the infrared source (Figure 6), which are not the ideal source for sensors. Firstly, the initial light intensity varies greatly between units, making deployment challenging. Secondly, they suffer from inherent instability: tungsten evaporates from the thin filament and adheres to the glass surfaces, blackening the bulb walls ...

Low Cost IR CO2 Sensors -

This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent performance to a conventional dual-channel CO2 sensor…

IR vs TC: Settling the CO2 sensor debate once and for all ...

· Therefore, opening the door of the CO2 incubator easily affects the sensor, leading to inaccurate measurements. IR Sensors. IR sensors, on the other hand, operate on the theory that light is absorbed by gases at specific frequencies. For instance, light is absorbed by CO2 at μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a filter. Higher CO2 …
