Miniature Infrared Carbon Dioxide Sensor KGD-SRH-210
Product Introduction
The Miniature Infrared Carbon Dioxide Sensor KGD-SRH-210 is an industrial-grade gas sensor used for real-time measurement of changes in gas concentration. It adopts the infrared gas sensor technology (NDIR). Compared with the thermal catalytic and semiconductor principles, it has remarkable features and advantages such as a good signal-to-noise ratio, strong selectivity, immunity to cross-gas interference, high precision, excellent long-term stability, and a long service life. It meets various usage requirements in industrial sites, laboratory measurements, etc.
