20190601· The new multisensor NDIR was probed to measure carbon dioxide (CO 2) and methane (CH 4) from river sediments in situ. • A gas extraction chamber was designed and built based on the biogas yield under the extraction by ultrasound. • The specific methanogenic activity was measured to evaluate the biogas yield. Abstract. A novel multisensor infrared nondispersive was developed and …


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. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...

While NaCl has a melting point of 801 °C, the melting point of Na2SO4 is higher (888 °C). The potassium salts of sulfuric acid also have a significantly higher melting point than those of hydrochloric acid. This has a positive effect on the lifetime of the combustion tube. Compound Melting point NaCl 801°C KCl 773°C Na2SO4 888°C MgCl2 708°C

NDIR Gas Sensors Electrical Optical Components, Inc.

An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not prefiltered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using one of the following technologies: Thermopile ...
