Design of A Handheld Multifunctional Gas Analyzer

In order to accurately measure the content of various components in flue gases released in industial burning,a portable multifunctional gas analyzer was designed with LPC2214 as the core of its hardware,which was responnsible for controlling the whole system.The software program was modularized.The new gas analyzer can measure and store the real-time temperature and the pressure in monitoring the type of air polutants and their content,which enables the new analyzer to provide comprehensive information about the tested gases.The analyzer is powerful,portable and easy to operate.
