YAW Computer-Control Automatic Compression Testing Machine
Application:
The model YAW-300B can be used in the compression strength testing of cement mortar, while the model YAW-300C can be used in the compression and bending strength testing of cement mortar. Control method of testing rate is electro-hydraulic closed-loop control.

Features:
1. Driven by servo motor, this product avoids leak and blocking of servo valve contracting to the traditional hydraulic type.
2. Zero noise
3. Testing the force by load sensor, the measure range can be as 2% to 100% of the full measure scale, with high accuracy.
4. Equipped with well-found position limitation protection, overload protection, emergency shut-down and other safety protection function.
