The instrument is designed according to my country's national standard GB/T2679.5-1995 (determination of folding endurance of paper and cardboard). The instrument adopts photoelectric control technology to make the folding chuck return automatically after each experiment, which is convenient for the next operation. The instrument has a powerful data processing function: it can not only convert the bifold times of a single sample and the corresponding logarithmic value, but also can count the experimental data of multiple samples in the same group, and can count the maximum value, Minimum value, average value and coefficient of variation, these data are stored in the microcomputer and can be displayed through the digital tube. In addition, the instrument also has a printing function.
