Description

ASTM D4491 Geotextile Vertical Permeability Performance Tester Geotextiles Permeability Coefficient Lab Testing Machine

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.

4. Control method: Single-chip microcomputer program automatically controls temperature.

5. Clamping method: Vertical.

6. Built-in dissolved oxygen sensor, which can directly display the oxygen concentration of the liquid.

7. The instrument is equipped with a built-in vacuum pump, which can effectively reduce the oxygen concentration of the liquid.

8. Water collection methods can be selected as flow meter or manual water collection.
