水柱型Oken型透氣性/光滑度測試儀 KY / KG / KB 系列使透氣性（透氣性）和紙，聚合物薄膜和無紡布等各種片狀材料的平滑度易於操作。它是可以在短時間內進行測量的測試儀。
通常用於測量透氣度或平滑度的Gurley透氣度測試儀和Beck的平滑度測試儀可測量一定量的空氣通過板材的時間。另一方面，Oken型測試儀使用少量的空氣流過片材，並基於片材前後的壓力差來計算透氣度和平滑度。由於測量方法的這種差異，Oken型測試儀的特點是可重複性高，並且測量時間比Gurley測試儀或Beck測試儀短。考慮到這些特徵，Oken透氣度測試儀在JIS P8117：2009中被規格化，而Oken平滑度測試儀在JIS P8155：2010中被規格化。

Oken Type Water Column Type Air Permeability/Smoothness Tester
《Features》
1. Measuring time is under 1/50, comparing with Air Permeability / Smoothness of Gurley type.
2. Measure more rapidly with combination of options.
3. Accurate measurement from high second (up to 10,000s) to low second (around 1 sec) in Air Permeability and Smoothness.
4. Applicable for not only papers, but filters, polymer films, non woven and other products.
5. No influence to test specimen by measuring with 1/10 pressure of JIS type Bekk tester.
6. Accurate and stable measurement by basic water column type manometer
7. Easy maintenance
