ASTM D4491 Geotextile Vertical Permeability Performance Tester Geotextiles Permeability Coefficient Lab Testing Machine
Scope of Application
The geotextile vertical permeability performance tester is designed and manufactured in accordance with the latest national standard GB/T15789-2016. It is a constant head tester suitable for testing the vertical permeability performance of various geotextiles and composite geotextiles under constant water head. This machine adopts microcomputer program control, with sensors to collect and measure water volume, and automatically calculates the permeability coefficient.
Compliance Standards
GB/T15789-2016, ASTM D4491-2017 Method A - Constant Head Test
Instrument Features
1. Human-machine interface: Touch screen operation, menu-based operation, simple and clear.
2. Cooling method: Imported compressor.
3. Protection function: Equipped with a water level device, with anti-dry burning function.
