Overview

Concrete High and Low Temperature (Compression) Universal Testing Machine Number: LHWS-860A Brand: Lingye Instrument/LINKEAR Specification: Type: High and Low Temperature Test Chamber Introduction: The microcomputer controlled concrete high and low temperature universal testing machine can perform tensile, compressive, bending, shear and other types of tests on different materials or products at different environmental temperatures according to GB/ISO/ASTM/JIS/DIN/EN standards. Adding functional accessories can complete various tests on materials such as steel bars, components, cement, concrete, bricks, tiles, etc. Add high and low temperature environment test chambers or high temperature furnace test devices, capable of conducting multiple high and low temperature tests such as high temperature tensile test, high temperature compressive test, and high temperature bending test. Equipped with Youhong full digital closed-loop control system, it can automatically obtain performance indicators such as tensile strength, compressive strength, yield strength, specified non proportional tensile strength, elastic modulus, etc. of the tested material (or program control as needed), and can achieve equal rate loading, constant rate deformation, and constant rate positioning

IIConcrete high and low temperature (compression) universal testing machineAccording to the standard:

The Lingye testing machine complies with the requirements of GB/T2611 "General Technical Requirements for Testing Machines", GB/T16826 "Electro Hydraulic Servo Universal Testing Machine", GB228 "Tensile Test Method for Metallic Materials at Room Temperature", GB/T232 "Bending Test Method for Metals", GB/T7314 "Compression Test Method for Metallic Materials at Room Temperature", GB/T50081 "Standard Test Method for Mechanical Properties of Ordinary Concrete" and other standards.

IIIConcrete high and low temperature (compression) universal testing machineSafety protection device:

1. When the test force exceeds 2% -5% of the maximum test force for each gear, overload protection is activated and the system is unloaded.

2. When the piston rises to the upper limit position, the stroke protection stops and the oil pump motor stops.
