口罩BFE测试机

口罩BFE测试机用于以特定流速测试包含细菌悬浮颗粒的材料的百分比。
特征:
1.面罩BFE测试机:负压测试系统,可以保护操作人员的安全。
2.蠕动泵内置在负压柜中,A,B通道流量为28.3L / min。
3.可以设置蠕动泵的流量。
4. BFE Tester雾化效果好。
口罩BFE测试机测试原理:
细菌过滤效率测试仪由气溶胶产生系统,气溶胶室和气溶胶传输装置,负压柜,28.3 l / min碳采样器等组成,整个检测器由控制台控制,控制台采用微电脑控制系统协调和控制气溶胶产生系统,传输系统,负压柜和采样系统的工作,并实时显示工作状态。整个测量工作是自动完成的。

适用标准
  • ASTM F2100标准规范,用于医用口罩的材料性能
  • 要求欧洲医用口罩符合EN 14683标准
  • 使用金黄色葡萄球菌生物气溶胶评估医用口罩材料的细菌过滤效率(BFE)的ASTM F2101标准测试方法
  • YY0469-2011口罩技术要求
  • YY / T 0969-2013一次性医用口罩
