NDIR CO2 Sensor NDIR is an industry term for “nondispersive infrared”, and is the most common type of sensor used to measure carbon dioxide, or CO2. The CO2 sensor works by directing light waves from an infrared lamp through a tube filled with air samples. This air moves 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 radiation also produced by the lamp is very close to the 4.26-micron absorption band of CO2. Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or “fingerprint” to identify the CO2 molecule. As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass through. At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the wavelength ... Continue reading →

NO2 electrochemical sensor-Nitrogen dioxide leakage will cause great environmental pollution to the natural environment and threaten the personal safety of actual operators. Therefore, NO2 electrochemical sensors must be used. With the development trend of my country’s electronic component technology and the rapid development of well-known Chinese companies. Gas sensors have been widely used in various fields. So which fields are NO2 electrochemical sensors used in? Applied in chemical manufacturing industry In the chemical manufacturing industry, nitrogen dioxide can be used as a refrigerant for refrigeration units and a raw material for manufacturing fertilizers. Due to long-term disrepair and lack of innovative management. It is inevitable that nitrogen dioxide will leak. According to incomplete statistical analysis. The annual leakage of nitrogen dioxide amounts to 2.1 to 8.1 tons. Nitrogen dioxide leakage will cause greater environmental pollution to the natural environment ... Continue reading →
