Environmental Triaxial System

The VJ Tech Pro Temperature Controlled Environmental Triaxial System delivers automated total and effective Temperature Controlled Triaxial testing for Consolidated Drained (CD), Consolidated Undrained (CU), and Unconsolidated Undrained (UU) tests. It operates within a temperature range of -20°C to +80°C, regulated by the remotely operated Temperature Control Unit (TCU) which maintains precise temperatures using a 50/50 antifreeze and de-aired water mixture.

 

Description

The VJ Tech Pro Temperature Controlled Environmental Triaxial System delivers automated total and effective Temperature Controlled Triaxial testing for Consolidated Drained (CD), Consolidated Undrained (CU), and Unconsolidated Undrained (UU) tests. It operates within a temperature range of -20°C to +80°C, regulated by the remotely operated Temperature Control Unit (TCU) which maintains precise temperatures using a 50/50 antifreeze and de-aired water mixture.

This Environmental Triaxial System boasts a corrosion-resistant, insulated Triaxial cell capable of withstanding pressures up to 2000 kPa and supports up to 10 analogue input channels. The Pro Dual Automatic Pressure Controller efficiently manages both cell and back pressure and volume. Additionally, the Clisp Studio software enhances test management and data collection, offering extensive options for configuration and results export.
