LTB-2S Microcomputer-Controlled Rock Elastic Modulus and Poisson’s Ratio Testing Machine

Description

Product Introduction

Suitable for compression testing under rated test forces, it can also perform tests to determine the elastic modulus and Poisson’s ratio of rocks, enabling the measurement of the elastic modulus (E) and Poisson’s ratio (ν) of rock materials. It is widely used for mechanical property analysis in geology, mining, construction, and other fields. The equipment can measure parameters such as the elastic modulus, Poisson’s ratio, and compressive strength of rocks under static or dynamic loading; certain models support multiple test types, including tension, compression, bending, and shear.

Compliant with standards such as GB/T 228, GB/T 50266, SL/T 264 “Test Procedures for Rock in Hydraulic and Hydroelectric Engineering,” and JTG/E 41 “Test Procedures for Rock in Highway Engineering,” this equipment is suitable for rock mechanics research in coal mining, transportation, construction, and other fields. With the aforementioned technical configuration and a variety of testing methods, the device can meet the high‑precision analysis requirements for rock mechanical properties across diverse application scenarios. Equipped with two transverse and two longitudinal displacement sensors (with the number of sensors customizable upon request), it directly measures the deformation of the rock specimen and transmits the data to a computer in real time, automatically saving various curves that can be retrieved at any time as needed, including stress–strain curves.
