Frequently Asked Questions (FAQ)
Q1: Can this machine perform both tensile and compression tests?
A: Yes. It features a single-space design; by adjusting the testing space, it can perform tensile and bending tests on metallic materials as well as compression tests on concrete, making it ideal for comprehensive laboratories.
Q2: How is the testing space size adjusted?
A: The equipment is equipped with a movable lower grip assembly. With a lifting speed of up to 300 mm/min, it can quickly adjust to the appropriate testing height based on the sample size.
Q3: Is the equipment difficult to maintain?
A: No, it is not complex. Its external cylinder grip structure facilitates easy observation and routine cleaning. Furthermore, as a professional manufacturer, Zhejiang Yiyu Instrument Equipment Co., Ltd. has established a dedicated pre-sales and after-sales service system to ensure the equipment's long-term operation.
Q4: Why is the 1000B model significantly heavier than other models?
A: The WAW-1000B is designed to withstand test forces of up to 1000 kN; consequently, its main structure is larger and more robust (weighing 2100 kg) to ensure testing accuracy and structural safety under maximum loads.
Q5: Are the measurement data reliable?
A: Yes, they are reliable. The equipment meets Class 1 accuracy standards, with a relative indication error within ±1%, and complies with multiple rigorous national technical standards, including GB/T 16826.
