摘要
在YA-1型肺通气量仪上增设一个粉尘采样器,使该仪器既能测定肺通气量,又能测定空气中的粉尘浓度。它是在操作工人的呼吸带采样的,因此,能真正代表个人实际接尘量。
The addition of a dust sampler to the Respiratory Volume Meter makes it Possible to measure both respiratory volume and dust concentration in air. As the sampler is operated by respiration of the user, it gives actual dust exposure of the user.
