NDIR CO₂ Sensor | セラミック [Nippon Ceramic Co., Ltd]

1. NDIR Measurement Principle. NDIR CO 2 sensor uses the principle that the gas to be measured absorbs infrared rays in a specific wavelength range, and the degree of absorption depends on the concentration. NDIR is an abbreviation for Non-Dispersive InfraRed. Infrared rays emitted from the light source are measured by an infrared detector after passing through the gas.

Measuring Carbon Dioxide (CO ) Using Non-Dispersive ...

In an NDIR sensor measuring CO˚, a Wavelength Filter placed just before the IR Detector only allows that wavelength of IR energy absorbed by CO˚ to pass through. The IR Detector measures the concentration of that wavelength of IR light after it has passed through the sample. Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy ...

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element is used to separate out the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the gas …

Non-Dispersive Infrared (NDIR) Spectroscopy . Non-Dispersive Infrared (NDIR) spectroscopy is a measurement technique used to non-invasively detect gas concentrations. Depending on their molecular composition, polyatomic gases possess the ability to absorb electromagnetic radiation at specific wavelengths in the infrared region. NDIR spectroscopy utilizes this ability to determine the measured gas
