How NDIR CO2 Sensors Work. NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice.
Knowledgebase. NDIR Principle. Non-Dispersive Infra-Red (NDIR) detectors are the industry standard method of measuring the concentration of carbon oxides (CO & CO2). Each constituent gas in a sample will absorb some infra red at a particular frequency. By shining an infra-red beam through a sample cell (containing CO or CO2), and measuring the ...
The CO12e analyzer is an Eco-designed, reference air quality monitor, QAL1 certified by the TÜV, US-EPA approved and compliant with ISO 4224. It offers superior metrological performances for CO measurements in the range 0-300 ppm. CO 2 monitoring as an option (range: 0-2000 ppm by NDIR) CO12e dilution quantity. Add to Compare.

Aug 14, 2021· Adafruit SCD-41 – NDIR CO2 Temperature and Humidity Sensor – STEMMA QT / Qwiic. The SCD-41 is a photoacoustic ‘true’ CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn’t approximating it from VOC gas concentration – it really is measuring the CO2 concentration!

NDIR SENSORS: NDIR – the most complete range of Infrared (IR) gas sensor on the market for CO2, SF6, hydrocarbon and refrigerant gases. We make no mystery about it: Non-Dispersive InfraRed (NDIR) technology is at the core of our DNA. This is completely designed and manufactured at the headquarters in Milan, Italy and our staff ...
The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
