DRK111B Schopper Folding Tester

Product introduction

DRK111B folding tester is designed according to relevant standards and adopts modern mechanical philosophy and computer processing technology. It has LCD display function, various parameters setting function, conversion, adjust, memory, printing and other functions。

Product features

New drive system and cooling system;

Temperature sensor monitors test temperature;

Two kinds of folding head to improve test efficiency;

Test data can be displaced by LCD, stored in micro-computer and printed by micro-printer.

Analyze Max. value, Min. value, average and coefficient of variation of a group test results.

Judge the break state and repeated folding number before breaking;
Silent Motor drives the folding head;

Precise bearing drives cutter to ensure steady running and good repeatability;

The test will stop and the folding knife will return back automatically after test.

Product application
