摘要
介绍非分光方法测量大气二氧化碳浓度的方法,选用光源器件EMIRS200,并对它的脉冲调制驱动电路进行设计。然后,将其用于测量二氧化碳气体,并用EC9810型二氧化碳分析仪的观测结果对它进行标定,初步获得了较好的结果。结果表明,试研制的光源具有用于气球探空的潜力。
In this paper method for CO2 measurements based on non-dispersed infrared（ NDIR） was described. A pulse modulation circuit was designed to fit the chosen light source EMIRS200. Then a CO2 measurement was conducted with the designed light source. With an EC9810 CO2 analyzer,calibration of this setup was carried out,and a good comparison results was achieved. Due to its small volume light weight and stable emission intensity,experimental results show that EMIR200 has a good potential in CO2balloon-sonde.
