- 产品介绍

Versatile Filters Uniquely Suited for a
Broad Range of Air Monitoring Applications- 适合高温及热气体空气监控应用。
- Ideal for stack sampling and diesel emissions testing.
Tissuquartz 过滤器
- Heat treated for reduction of trace organics and superior chemical purity.
- High temperature use for analysis of acidic gases and stack sampling aerosols.
- 大流量及高过滤效率。
- Ultra-pure soft water processing to reduce residual ion content.(Contact 颇尔 Technical Service for typical values.)
Fiberfilm 过滤器
- Economical filter suited for a range of air sampling applications.
- Moisture variations in air or gases during air sampling will not cause chemical reactions on the filter.
- Heat-treated (HT) version available for reduction of trace organics.
Emfab 过滤器
- 可承受重量及运输中的折叠。
- Every filter flushed with DI water to remove water-soluble residue.
- Low air resistance for use in critical aerosol sampling tests such as diesel exhaust.
