Performance characteristics: 1. High-precision, low resistance, to reverse zero clearance and linear low driving force to ensure extended service life; 2. High-precision control and repeatable measurement results ensure a more realistic reflection of the specimen characteristics; 3. Four-column double-screw double space rigid frame structure, linear travel to ensure the crosshead neutral, thereby reducing test data error, raise experimental accuracy; 4. The digital closed-loop position control servo motor and gear reducer drive mechanism, the servo motor having a large torque output can be realized in a wider load range of high-precision speed control, quick response and full performance; 5. The high degree of intelligence system has a self-diagnostic function. It can automatically detects over-voltage, over-current, over-temperature; 6. Automatic hydraulic grip prevents sample slippage. The adjustable gripping pressure prevents damage to the soft material specimen to improve the accuracy of test results; 7. Optional double cylinder synchronous hydraulic grip, huge clamping force, specimen doesn’t slip. The adjustable pressure to prevent damage to the soft material sample, improving the accuracy of the test results; 8. High-precision tension and compression bi-directional load cell, strong resistance to lateral and impact; 9. There are dozens of different types of fixtures, to meet the different requirements of various industries material testing; 10. Aluminum cover for easy cleaning and a long-lasting-life;
