Miniature Infrared Carbon Dioxide Sensor KGD-SRH-200
Miniature Infrared Carbon Dioxide Sensor KGD-SRH-200
Product Introduction
The KGD-SRH-200 series of miniature infrared carbon dioxide sensors is a miniature gas sensor used for real-time measurement of gas concentration changes. It employs the Non-Dispersive Infrared (NDIR) detection technology and has remarkable characteristics 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 lifespan. The sensor features a digital serial port output function, meeting various usage requirements in industrial sites, laboratory measurements, etc., and is widely applied in fields like environmental monitoring and healthcare.
