  • Non-Dispersive Infrared Gas Analyzers (NDIR) | BBP Sales

    The IR200 infrared gas analyzer is capable of measuring the concentrations of CO2, CO, CH4, SO2, NO and O2 components in sample gas. CO2, CO, CH4, SO2 and NO are measured by the non-dispersive infrared method (NDIR), while O2 is measured by the paramagnetic or zirconia method. A maximum of 4 components including O2 (up to 3 components except for O2 measurement) are simultaneously measurable.

  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

  • NDIR Sensor for Non-Dispersive Infrared Detection

    IR Gas SensorsNon-Dispersive Infrared (NDIR) SensorsEliminating ErrorsAre You Looking For An Ndir Sensor?Commercial IR gas sensors generally consist of an infrared source, a detector, a gas cell/path, a wavelength selection device and some optical components (lenses or more usually mirrors) to couple the radiation from the source through the gas cell to the detector. The sample gas passes through the gas cell and the detector measures the radiation at the absorption band wavelength of the target gas. When no target gas is present there is no absorbance so the signal reaching the detector is at a maximum. When the target gas is present in the path, the detected signal reduces as the target gas concentration increases.

  • Complete Gas Sensor Circuit Using Nondispersive Infrared (NDIR)

    Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the concentration of the gas component can be determined.

  • A review on non-dispersive infrared gas sensors: Improvement

    Aug 01, 2016 · Detection limit is a measure of the smallest concentration which can be determined with a specified precision or reproducibility. The detection limit of a NDIR sensor is a function of both IR signal strength (or sensitivity) and signal stability (signal-to-noise ratio). The detection limit has a concentration unit such as ppb, ppm, μg/m 3. The precision (%) of a NDIR sensor shows the consistency of results when repeated.
