Oken type smoothness and air permeability tester (digital type)
Physical testing / Roughness/Porosity
  • No.2040-C
  • [JIS]P-8155-2010,P-8117-2009
  • [TAPPI]
  • [ISO] 5636-6
This machine, like the H model, is designed to determine smoothness and air permeability by converting to pressure the airflow between the standard surface and the surface of a specimen under certain conditions. The digital model uses an electronic manometer instead of the water column type air manometer, displaying smoothness and air permeability as a digital value.
In addition, use of the timer enables to display measurement values always in stable status.
This machine is optimal for field management with the following advantages;
Measurement in short time
Easy in reading measurement values, because they are expressed as digital values. The tester for smoothness only or for air-permeability only also is available.
Oken type smoothness and air permeability tester (water column type)
Physical testing / Roughness/Porosity
  • No.2040-H
  • [JIS]P-8117-2009
  • [TAPPI]
  • [ISO] 5636-6
This machine has its characteristic in using a 500mm water column air manometer to measure airflow between the surface of a specimen and the standard surface, with certain conditions, while Bekk type smoothness tester depends on the measurement of time that is needed to inflow a certain amount of air.
The standard surface is constituted of multiple concentric rings, and the air of 500mm water column-adjusted low pressure is let to flow between the standard surface and the specimen for measurement. On the way of the air passage, is provided a capillary orifice to convert airflow into pressure for display. This testing method consumes little time in measurement, so it is suitable for site management. The standard type measures smoothness and air permeability. The tester for smoothness or air permeability only is available.
