摘要
介绍了合格滤筒的筛选方法和采样滤筒在实验室分析中的质量控制,分析了影响滤筒称量恒重的原因,指出空气湿度、冷却时间和烘干时间对滤筒称量恒重都有影响。
The authors described the function of barrellike filter in sampling for smoke dust monitoring, screening method for the certified and laboratory quality control for sampling barrelike filters. Some effect factors may influence constant weight of barrellike filters such as air humidity, time spending for drying and cooling the filters.
