Features: 1. Touch screen control technology, open structure, high degree of automation, simple and convenient operation, safe and reliable; 2. The paper breaking strength tester, independent research and development software, automatic measurement of breaking resistance, intelligent calculation function, statistics, printing test results, and unique pressure difference parameters (which can ensure the accuracy of the test); 3. It has data storage function and large data storage (500 groups, 20 samples per group, 10,000 groups of data can be stored for later query); 4. High-speed micro printer, high-speed printing, easy to use, low failure; 5. The sample is automatically blessed, saving time and effort, and reducing human error; 6. The modern design concept of mechanical and electrical integration, hydraulic system (the cylinder is made of copper and steel with 4-layer seal to ensure no oil leakage to 6000kpa), powerful function, compact structure, beautiful appearance and easy maintenance. Applications: It is used to test all kinds of cardboard and single-layer and multi-layer corrugated cardboard. It can also be used to test the breaking strength of non-paper materials such as silk and cotton cloth.
