    Tips: Advantages of NDIR CO2 Sensor。

    Infrared gas sensors and instruments are suitable for monitoring various flammable, explosive, and carbon dioxide gases, and have significant advantages such as high accuracy, good selectivity, high reliability, no poisoning, no dependence on oxygen, less environmental interference, and long life. . These advantages will lead to electrochemical and infrared gas detection instruments occupying a wider high-end market in the industry, and will gradually become the mainstream of the market in the future. The above is the fault analysis of infrared gas sensors introduced by sensor enthusiasts. In the field of gas sensors, related research and development technologies are developing and improving rapidly. It is believed that infrared gas sensors will become more and more advanced in the future, and abnormal failures will occur at the same time. It will be less and less!
