MIT Folding Endurance Tester is used for determining the folding endurance strength of paper and paperboard using hang type weight method.
This machine has various functions, such as, parameter testing, parametric transformation, parameter regulation, parameter display, parameter memory and parameter print. The tester has data processing function which can directly output result of statistical data with convenient operation, easy regulation and stable performance.
The main functions are shown as following , compact structure, light weight, abundant functions, horizontal type and stable performance, so the tester is suitable for different paper and boards.
