Geotextile equivalent aperture tester (wet sieve method)

Campo di applicazione:

The equivalent pore diameter of geotextile and its related products was determined by wet screen method. The geotextile sample without tension is used as the screen, and the sample and graded particle material are sprayed with water under the specified vibration frequency and amplitude to make the graded particle material pass through the sample. The effective pore size of the specimen is expressed by the specific particle size of the passing particle material.

Soddisfare lo standard:

GB/T17634-2019,ISO/FDIS 12956-1998,etc.

Caratteristiche dello strumento:

It is suitable for the determination of effective aperture of various geotextiles.

Split type design is adopted to avoid damage to the control system caused by vibration during high-speed operation;

The parts are connected with aviation plug, easy to disassemble and assemble;
