The design and test results of a simple carbon monoxide detector based on the reducing gas detector principle are presented. This instrument has several features which distinguish it from similar carbon monoxide analyzers, all of which contribute to its usefulness on small airborne platforms such as kites, balloons, and light aircraft. Compact size, battery operation, low cost, and light weight are among the most important improvements made over to earlier systems. The instrument fits a package 10 x 20 x 25 cm, has a mass of 2.0 kg, and consumes an average of 20 W of power. This instrument will, therefore, offer a means of incorporating carbon monoxide measurements in recoverable or disposable balloon sondes. The instrument makes an independent measurement of carbon monoxide every 8 s, with a sensitivity of 3 ppbv carbon monoxide (limit of detection for S/N = 3) and a precision of 4%.
介绍了一种基于还原性气体检测原理的简易一氧化碳探测器的设计与测试结果。该仪器具有一些使其有别于类似一氧化碳分析仪的特性，所有这些特性都有助于其在风筝、气球和轻型飞机等小型空中平台上发挥作用。紧凑的尺寸、电池供电、低成本和轻重量是相对于早期系统最重要的改进之处。该仪器可装入一个10×20×25厘米的封装中，质量为2.0千克，平均功耗为20瓦。因此，该仪器将为在可回收或一次性气球探空仪中纳入一氧化碳测量提供一种方法。该仪器每8秒独立测量一次一氧化碳，一氧化碳灵敏度为3 ppbv（信噪比S/N = 3时的检测限），精度为4%。
