Oken Type Smoothness and Air-permeability Tester (Digital)

Description

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.
