EN 10002-2, BS1610, DIN
51221.
2. Displacement measurement: adopts optical encoder with high
accuracy and stability;
3. Strain measurement: Adopt high accuracy electronic extensometer:
Strain measurement meets or
exceeds the following standards: ASTM E83, ISO 9513, EN 3846 and EN
1002-4.
4. Compact structure: with dual testing spaces and easy to adjust
testing space to carry out different test
of varying-length specimens; The machine has four column and two
screw with strong stiffness;
5. Clamp automatically: uses hydraulic grips with reliable holding;
6. Multi-protection: protection of over-load by software and
hardware; position-limited protection of piston
and lower crosshead;
7. Test report can be acquired according to requirements of
customers;
8. Management of test data: uses Access, Excel and other such kind
software to communicate with
testing data base;
9. Stable performance with little influence of temperature and
voltage;
10. Multiple Servo control mode : Load (Stress) Control;
Displacement (Stroke) Control, Strain
(Deformation) Control. Load keeping, Displacement Keeping,
Customized programming Control, etc
