Digital California Bearing Ratio Apparatus CBR Load Ratio Tester Apparatus

1. 10.1 inch color touch screen display, with curve display, data saving and printing.

2. At the same time, it supports two international standards and domestic standards

British Standard BS 1377-4, American Standard ASTM d1883 and national standard t0134-1993

3. It can set the deformation record point and loading speed arbitrarily to meet the needs of different test standards.

4. With data processing function, CBR value can be calculated automatically.

5. Servo motor control, with software speed feedback, loading speed stepless regulation.

6. Built in micro printer can print data stream list and test results.

7. Digital dial indicator can be selected to further improve the test accuracy.

8. PC version test software can be selected, and PC software can be used for independent test and output detailed report.
