Infrared NO2 gas sensor is a NO2 sensor using the infrared absorption detection principle. The infrared NO2 gas sensor adopts the imported light source, the optical cavity with special structure and the two-channel detector to realize the reference compensation of the space dual optical path. The linear error is better than ±1% of the full scale and the zero drift is small. NDIR nitrogen dioxide sensor has the characteristics of good selectivity, high sensitivity, no oxygen dependence, long life and low power consumption. Plug and plug installation is adopted to facilitate customers’ various applications.
1. Large range monitoring
The good selectivity of the product makes up for the shortcomings of traditional electrochemical sensors in the selection of high range test range.
2, not afraid of harsh environment
Using imported infrared light source and double channel pyroelectric measurement, and can automatically carry out temperature compensation function, even in the harsh temperature and environmental conditions, can also get stable and reliable measurement results. High temperature resistance (80°C), suitable for coal mine, oil field, chemical industry and other types of flue gas environment.
3. No significant life time limit
NDIR sensor has no obvious consumption compared with traditional electrochemical sensor. The electrolyte on the sensor will not be depleted due to long-term exposure to target gas or interference gas crossing, and the service life is long.
