Phoenix TMI Triax Automatic Triaxial Testing Machine
PHOENIX TMI TRIAX AUTOMATIC TRIAXIAL TESTING SYSTEM
Proudly researched, developed, and manufactured 100% in Vietnam, the Phoenix TMI Triax Automatic Triaxial Testing System provides a comprehensive geotechnical testing solution for UU, CU, and CD tests. The system is designed to comply with international and Vietnamese testing standards, including ASTM, BS, and TCVN.
Phoenix TMI Triax is a fully automated triaxial testing system, operated through PNXSMT bilingual English–Vietnamese control software, making it intuitive and accessible for local engineers. The software also features automatic report generation, helping streamline the testing workflow while reducing testing time and operating costs.
Technical Specifications
Detailed Description
PNXSMT SOFTWARE ECOSYSTEM
PNXSMT software is developed to automate the entire triaxial soil testing process, providing real-time data monitoring, specimen management, and automated report generation for research and testing applications.

Control & Data Visualization
The software provides comprehensive control throughout the saturation, consolidation, and shearing stages of the test. Real-time data is displayed at a high sampling rate, enabling the system to capture even subtle changes in specimen behavior while reducing measurement errors and minimizing the effort required for data collection.
Intelligent Specimen Management
The software supports simultaneous data management for multiple test specimens. In particular, its saturation-level calculation feature helps minimize errors in determining when a specimen has reached the required saturation condition.
Automated Report Generation & Data Processing
The system automatically generates reports in PDF format using templates customized for each customer. Test data can also be exported directly to Excel, with automated data interpolation capabilities to support advanced geotechnical analysis.
STANDARD SYSTEM CONFIGURATION

Designed and manufactured in Vietnam, the system consists of independently operating modules that are seamlessly integrated to ensure highly reliable test results. Phoenix TMI Triax includes the following modules:
Loading Frame: Equipped with the robust PNXTRIAX main loading frame, providing stable confining pressure from 0–1000 kPa.
Pressure Cell (TRIAX CELL): The pressure cell features a robust design for easy specimen installation and removal. Combined with the main loading frame, it maintains stable and consistent pressure throughout the test.
Pressure Generation Pump (PNXVPC S10): Generates pressure along the X and Y directions and works in conjunction with the main loading frame to establish a triaxial stress state within the specimen.
Data Acquisition Unit (CRVDAQ): Acquires data from pressure and force sensors and transmits it wirelessly to the computer, reducing cable clutter, saving workspace, and maintaining a clean laboratory setup.
EXPANSION & UPGRADE OPTIONS
To accommodate advanced and flexible testing requirements, Phoenix TMI offers comprehensive upgrade packages, ensuring your system is ready for larger and more demanding projects.
Optimized Saturation Process
The standard configuration can be expanded with a three-pump system and an air compressor. An additional solenoid valve system enables the specimen saturation process to be performed automatically.
SQL Data Monitoring & Management
The system can be integrated with a camera for direct specimen monitoring throughout the test. An optional SQL database integration provides comprehensive data storage and flexible retrieval across the entire laboratory system.
APPLICATION STANDARDS| COMPLIES WITH STRINGENT STANDARDS
A locally developed solution built to international quality standards, the Phoenix TMI Automatic Triaxial Testing System strictly complies with leading geotechnical testing methods and standards.
