Geotextile Tester

Pore throat testing of through holes in filter membranes, fibre membranes, filter cartridges, battery diaphragms, fabrics, nonwovens, paper, ceramics, sintered metals, rocks, concrete and other materials.

For the determination of the in-plane water flow of geotextiles and their related products at different normal pressures and standard hydraulic gradients.

High precision stepping motor is used for horizontal shearing.

Used for test the apparent opening size for a single layer geotextile or geotextile-related products, under the wet-sieving principle.

The flow rate (MM/S), which is perpendicular to the plane flowing by the plane of the gear fabric under the hydraulic gradient of the unit.

1, By the large screen color touch screen separate control test, can also be used for computer control test, the computer can display real-time differential pressure - dynamic curve;
2, The use of high-precision imported micro pressure differential sensor, accurate measurement results, good repeatability;
3, Fully realize the automatic measurement, the sample to the specified position, the instrument automatically find the appropriate measurement range, automatic adjustment, accurate measurement.
4, Pneumatic clamping sample, fully meet the clamping requirements of various materials;
5, The use of long arm clamping handle, can measure large samples, and do not have to cut large samples small, greatly improve the work efficiency;

It is used for the determination of the thickness of geosynthetics and related products under different pressures and specified times, and supports a large range of tests with a maximum thickness of 40mm.

Used for testing the abrasion resistance of geotechnical materials.

En la muestra de geomembrana de superficie rugosa, utilice un medidor de profundidad para medir la diferencia de altura entre la parte convexa (pico) y la parte cóncava (valle) de la superficie de la película, y tome el valor promedio de los valores medidos de todos los puntos efectivos. en la dirección del ancho de la muestra como superficie rugosa. Altura de rugosidad de la superficie de la geomembrana.

1 Color touch screen control, human-computer dialogue mode, easy to operate.
2 Six-unit design, 5 workstations in each unit, high testing efficiency.
3 The six units can be tested separately and operation is simple. Built-in water circulation makes the temperature in the bath uniform and no big fluctuation.
4 Each workstation is equipped with a separate photoelectric switch to automatically determine the pause and record the pause time.
5 The temperature control adopts PID algorithm with small fluctuation, which effectively avoids over-temperature.
6 The instrument has a water level sensor for automatic monitoring to avoid dry burns caused by the absence of water.

This instrument is suitable for measuring the effective pore diameter of all types of geotextile products, and its performance meets the requirements of the national standard GB/T14799-2005, "Measurement of effective pore diameter of geotextiles and related products - dry sieving method" JTE-50. Principle: Take the sample of single-layer geotextile and its related products without tension as the sieve, under the specified vibration frequency and amplitude, conduct tests on the sample and graded granular materials to calculate the sieving rate.

Flow velocity of water flowing perpendicular to the plane of the geotextile under a unit hydraulic gradient (mm/s)
