离子烟尘密度计是测量烟尘密度的仪器。由我院和公安部沈阳消防所联合研制的FH4503型离子烟尘密度计已被指定为国家烟密度的标准测量仪器,并用作国家统一规定的标准测量方法。离子烟尘密度计主要应用放射性物质的电离电流流过烟尘时发生变化的原理。电离
Ion soot densitometer is an instrument for measuring soot density. FH4503 ion soot densimeter jointly developed by our institute and Shenyang Fire Department of the Ministry of Public Security has been designated as the standard measuring instrument of national smoke density and used as the standard measuring method stipulated by the state. Ion soot densitometers are mainly used when the ionizing current of radioactive material changes through the soot. ionization
