ASTM D4491 Method C
Application of TT-GMT2450C Geotextile Water Permeability Tester
Geotextiles and composite geotextiles
Features of TT-GMT2450C Geotextile Water Permeability Tester
- The LCD color touch screen can separate control test and can be used for computer control test. It can display real-time differential pressure – dynamic curve which is easy to control product quality.
- Equipped with high-precision imported micro pressure differential sensor it accurately measures results with good repeatability. It uses imported internal brands which can make the data comparison more reliable with less error.
- With fully automatic calculation of measurement range and auto adjustment.
- The pneumatic clamping sample fully meets the clamping requirements of various materials; the instrument adopts self-designed silencer to control the suction fan, which reduces solves the problem of large noise caused by large pressure difference of similar products.
- The instrument is equipped with a standard check hole plate that ensure the accuracy of the data.
- The use of long arm clamping handle can measure large samples, and do not have to cut large samples small, improving work efficiency.
- With special aluminum sample table and whole shell metal paint processing makes the whole machine durable and low maintenance.
- The instrument is easy to use, clear interface and simple operation.
