基于NDIR原理的红外CO浓度检测仪

该文介绍了一种基于非分散红外(NDIR)原理的红外CO浓度检测仪的总体设计,该检测仪使用新型红外传感器,以新型电调制光源代替机械调制光源,实现了对CO浓度的实时测量、LED显示和超限声光报警等功能,并通过后期的实验测试,验证了该检测仪在测量精度、范围等方面的优势。

Based on the principle of NDIR infrared CO concentration detector

Based on the introduction of a non-dispersive infrared(NDIR) The principle of a portable CO concentration detector design,the new detector using infrared sensors to the new machinery in place of electric light source modulation modulation source,to achieve real-time measurement of CO concentration,LED display and the gauge features such as sound and light alarm,and through the latter part of the experimental test,the validity of the detector at measurement accuracy,the advantages of scope.
