Constant Strain Stepless Speed Regulation Direct Shear Testing Machine on Soil
BACKStandards:
Applications:
This instrument is suitable for soil slow shear, fast shear and repeated shear tests.
Product Information:
The digital display constant strain controlled direct shear instrument is used to measure the shear strength of soil. Usually, a specimen is used to apply shear force under different vertical pressures to shear, so as to obtain the shear stress at the time of failure. The coefficient of shear strength, Angle of internal friction and cohesion are determined according to Coulomb's law.
Features
1. With hand shear function, can be in the case of power failure, does not affect the test.
2. Lever ratio amplification,.. The weight and the labor intensity of the weights.
3. Compact structure, reliable, stable and easy to use.
4. The instrument increased the shearing box back limit function, so that the shearing box back to the designated position after automatic stop, enhanced the protection function.
5. LCD display set shear speed, shear deformation.
