TSY-2geotextile effective aperture measuring instrument （ wet sieve ） is applicable to all types of geotextile products the effective pore size determination,

In line with national standards GB / T17634" geotextiles and geotextile-related products effective aperture - wet sieve" requirements.

Principle: to add tension monolayer of Geotextiles and geotextile-related products sample as a screen, in terms of the vibration frequency and amplitude,

On the specimen and graded granular material （i.e., sand ） are water, so that the particle size gradation of materials through the specimen
