| Abstract: | The system of concentration measurement of carbon monoxide based on a near-infrared spectrum absorption theory is presented. Common communication optical fiber is introduced into this system to transmit optical signal, and then the complication of designing optical-path is reduced. The principle, the structure and the main specifications of the instrument are introduced, and the technological feature and its corresponding advantage are discussed. Compared with the mid-infrared spectrum absorption, the total cost of devices is cut down greatly. |
