Computer-Control Servo Hydraulic Concrete
Compression Testing Machine

Specially designed for compression test of concrete. Precise control and easy operation is the basic principle of design.

High precision servo control and simple-operated program improves effectively the convenience and reliability of test.

Besides servo hydraulic model the types of traditional hydraulic & manual control with the display by computer monitor or digital indicator (available to disply load & stress speed) can be selected as optional.
