Computerized Constant Stress Compression Testing Machine

Model:TDYE-2000LZH

I. Product Introduction

This series of testing machines is designed for compressive strength testing of cement, concrete, and rock materials. With appropriate fixtures and measuring devices, it can also be used for concrete splitting tensile tests, flexural strength tests, and static elastic modulus tests. In addition, it is suitable for compression and end-face testing of metallic materials. The system can be expanded with multiple displacement or deformation measurement channels according to user requirements, meeting various complex testing applications.

The equipment complies with GB/T 7314-2005 “Metallic Materials — Room Temperature Compression Test Method”, GB/T 50081-2002 “Standard for Test Methods of Mechanical Properties of Ordinary Concrete”, and GB/T 50266-2013 “Test Methods for Engineering Rock Mass”.

Referenced or applicable international standards: ISO 604, ASTM E9, ASTM C39, and ISRM Suggested Methods.
