Automatic Microcomputer-Based Pneumatic Consolidation Tester (Loess Collapsibility)

This fully automatic pneumatic consolidation tester is used to measure the compressive properties of soil under varying loads and confined conditions. The system consists of a pneumatic consolidation tester, a pneumatic pressure controller, a multi-channel communication converter, and a data acquisition system.

    product description

    PRoduct description

    The soil Consolidation Test Apparatus can perform both normal slow consolidation tests and rapid consolidation tests, determining the initial consolidation pressure and consolidation coefficient. New features include: measuring the collapsibility coefficient, deadweight collapsibility coefficient, leaching deformation coefficient, and initial collapsibility pressure of loess. 

    Equipment Features

    The Consolidation Test Apparatus also allows for arbitrary setting (programming) of the rebound modulus, time period, and pressure range (loading and unloading). During the test, voice prompts (display) are provided for water injection, time period, and formatting.

    The consolidation Test Equipment system features stable and reliable pneumatic pressure control, low noise, separate control of consolidation pressure, and easy software installation.
