Geosynthetics Vertical Penetration Tester
Scope of application:
Used to determine the vertical permeability of geotextile and its related products under constant water head method. The water head of the instrument can be adjusted （0-300mm）， and can maintain a stable water head, the instrument is designed to reduce the loss of water head, using a box structure.
Meet the standard:
ISO 11058,ASTM D4491,GB/T 15789-2016,JTG E50 T1141-2006,SL/T 235-2012, etc
Instrument features:
Transparent design, easy to observe the test process;
Box structure, small head loss during testing:
The overflow lifting structure is used, which is easy to adjust the water head, and the water head is stable during testing.
Equipped with frequency conversion speed regulation flow system to ensure stable water head, and the maximum water head up to 300mm;
The use of plexiglass water tank can directly observe the test process of the sample;
The metering water tank has a scale line, which can directly observe the permeability of the sample and eliminate the steps and errors of the measuring cylinder.
Equipped with circulating water tank, water can be recycled to avoid the problem of large water consumption, energy saving and environmental protection;
Equipped with water recycling system, and frequency conversion speed regulation flow system;
The sample holder with two diameters of 52,100 mm avoids sample dispersion and is comparable with other early instruments.
Test program can be set, automatic test detection （DW1320S）;
Test data can be calculated and saved by itself, historical data can be queried and exported, and multiple test results can be compared （DW1320S）。
Technical parameters:
Sample diameter 52mm, 100mm
Water head 0——300mm adjustable
Sample thickness 0.1——10mm
Dimensions 1200x500x1440（LxWxH）
Weight 170kg
