The tester is designed according to the national standard of paper and cardboard folding strength testing.
It can automatically count the times of double folding on the sample. It takes photoelectric control to make folding gripper again after test and convenient for next operation.
The instrument has powerful data processing functions.
It can not only convert double folding times and single piece values, but also analyze the sample group data "to display the maximum, minimum, average and coefficient of variation.
The data stores in micro-computer displayed by LED.
In addition, it has the printing function.
