Product Desciption

Microcomputer stiffness tester
Product Usage :
The computer measurement and control stiffness tester is an intelligent computer stiffness tester suitable for measuring the bending stiffness of paper, cardboard and other strength sheet-like non-metallic materials with a thickness of less than 2 mm. The main technical parameters of the instrument comply with the relevant provisions of ISO2493 "Determination of paper and cardboard stiffness" and GB/T2679.3 "Cardboard stiffness measurement method".
Technical characteristics:
The angle can be arbitrarily set between (1 and 90) °, and the test time is arbitrarily set within a predetermined range (3 s to 35 s). With automatic zero test function, it is the first fully automatic stiffness tester for the 5.7in liquid crystal display curve in China. The real-time display stiffness and time curve are simple and convenient to operate. The instrument has the functions of test, display, memory, statistics and printing of various parameters included in the standard, and provides scientific data analysis for the detection of bending stiffness of cardboard.
