本文对LW-1型呼吸性粉尘采样头的现场粉尘浓度测定结果与日本TR粉尘采样头和总粉尘采样头进行了比较。结果表明三者的测定结果接近。此采样头可用于现场呼吸性浓度和总粉尘浓度的测定。
In this paper, the results of on-site dust concentration measurement of LW-1 respirable dust sampling head were compared with that of Japan TR dust sampling head and total dust sampling head. The results show that the three measurements close. This sampling head can be used for on-site respiratory concentration and total dust concentration determination.
