LDM-200 is a new extractable low-concentration particulates monitoring system, which can beapplied to measure low-concen-tration particulates after wet des-ulfurization and wet dustremoval in coal-fired power plants.
This instrument is based on the extractive scattering measurement principle and has extremelyhigh sensitivity. lt can reliably measure the concentration of particulates in the wet flue gasthrough the whole process of heat tracing sampling and the flue gas pretreatment module.
