PAO高效过滤器检漏仪 RI7001 Aerosol photometer
使用气溶胶光度计对高效过滤器进行检漏的原因
高效过滤器是无尘室洁净度得以维持的关键部件,所以高效过滤器的质量非常重要。其中最重要的就是它的简陋。方法比较多,有钠焰法,计数器扫描法,还有DOP检漏。
由高效过滤器下风侧泄漏浓度换算成的穿透率来衡量是否合格,其合格标准如下。因此,在安装好的净化空调系统中引入大气,是值得慎重思考的问题。因此,工程上检漏时会在高效过滤器得四周加放围挡,减小风口围挡下部出口面积时,围挡内形成一定正压。
气溶胶光度计产品介绍 Summary
Aerosol Photometer is a kind of special test instrument to test the leakage of HEPA, designed on the base of light scattering principle, displays real-time leakage rate by detecting aerosol concentrations of upstream and downstream. Applicable for testing clean rooms, laminar flow benches, biosafety cabinets, glove boxes, HEPA vacuum cleaners, HVAC systems, HEPA filters, ULPA filters, negative pressure filtration units, surgical suites, nuclear filter banks, collective protection filters, etc.
