Research On Portable Intelligent Gas-Analyzer

The exhaust of vehicle becomes one of the main source of air pollution now. With the increased demand for environmental ,the devices of gas analyzer are attracting more and more attention. The requirement of gas-analyzer becomes greater in our country. The gas-analyzers made in our country are 2-gas-analyser. The 5-gas-analysers are totally imported from aboard they are very expensive and hard to be maintained. Some of these devices are very huge and heavy. Some portable gas-analyzers are very expensive. For all of above, we developed a portable intelligent 5-gas-analyser to meet national market. We investigate many foreign 5-gas-analyser, and use the advanced single-light-routine system in the infrared system to detect gas. For use of CPLD in the digital circuit, the size of the device became very small.
