WCT-0504

• Safety protection-automatic detection of breakdown point while the test specimen breaks. Automatic stop once the test is complete.
• Equipped with safety cover.
• High Precision-Forces are measured with a precision proportion valve via a pneum-atic valve driver.  The pneumatic input range is within 1kg/cm2 ~ 8kg/cm2 being able to maintain high precise constant force. Adopt high accuracy and precision pneumatic pr-oportion valve to ensure test stabilities and low error.
• Selectable units of system-kg, N, lb
• Easy to Operate-The machine is operated via the corresponding POD(programmable operation display) system. One touch operation functions are easy for test.
• Conforms to national standard – Meets national standard requirement.
