【Abstract】 A sampling type smoke opacimeter has been developed based on Beer-Lambert law and the light extinctionmethod. In this paper, illustration is given to the concept of smoke intensity measurement by way of light extinction, thestructure and operating principle of the sampting type smoke opacimeter, the hardware circuit and software design flow ofa single chip microcomputer-besed measuiring system, and the scftware developed wsing VB object-Oriented program-ming languege for measurement and analysis of smoke intemsity.更多还原
