型號;QL-1003
自然堆積密度計依據(jù)國家標準GB/T 16913.3-1997???GB/T16913-2008的規(guī)定設計、生產(chǎn)。本裝置適用于粉塵堆積密度的測定。試樣的采集請參考GB/T 16913.1-1997 粉塵物理實驗方法第1部分：試樣粉塵的采集中的相關規(guī)定。

原理

粉塵從漏斗口在一定高度自由落下充滿量筒；測定松裝狀態(tài)下量筒內單位體積粉塵的質量，即粉塵堆積密度。

儀器結構

1、漏斗(流出口直徑12.7 )

漏斗不銹鋼材料制成，其中漏斗錐度為60°±0.5°。
2、測量架

不銹鋼材質，用于在粉塵裝入漏斗時防止粉塵下落。
3、天平（客戶自備）

最大稱量300g；精度0.01g。

4、量筒

本裝置配備一只容積為100ml的不銹鋼量筒，量筒內徑為Φ39mm。

5、刮板

不銹鋼材質，用于在粉塵裝入漏斗時去除多余的粉塵。

6、毛刷
