1. introduction
This compression testing machine is suitable for compression strength test of cement, concrete, brick, etc. And if equipped with suitable test fixtures, it can make test of splitting tensile test, flexural and bending test, static elastic modulus test etc.
2. features
- Adopting high rigid four columns structure, very stable during test.
- High precision load cell can make sure the accuracy and precision of test result
- Imported low voice high pressure oil pump to make a very quiet circumstance during test. Air cooling hydraulic system allows long working time of the testing machine.
- Adopting high integrated, powerful and high speed DSP platform, very strongly in data process.
- Full digital and three closed loop control system is based on self-adapting PID algorithm, which can realize digital closed loop control for force, deformation and displacement, and the three closed loop control can be switched freely without shock.

5. software introduction
5.1 compute auto control test procedures, software has functions of auto zero, calibrating, no grading in full capacity and speed adjusting. Software can measure test force, deformation, displacement, and display test curve in real time, process test data and print test report if connect to a printer.
5.2 display test curves of force vs time, force vs displacement, deformation vs time, etc.
5.3 functions of constant force speed control and load value holding, functions of displacement speed control and displacement holding
5.4 protecting function of sample breaking
