Abstract:Base on the problems existing in practical application of automatic monitoring instrument with TEOM for atmospheric particulate matter concentration, by analyzing its working principle, here aided plan designed for increasing number of light scattering components in the channel was put forward. The measured results showed that this method could improve the accuracy and efficiency of the instrument, enhance its stability and reliability, and make it more durable.
Keywords:TEOM  light scattering  abnormal value  accuracy  efficiency
