ZL-9049 Cardboard Paper Bending Stiffness Tester
Product Usage :
The microcomputer controlled stiffness tester is an intelligent computerized stiffness tester, which is suitable for measuring the bending stiffness of paper, cardboard and other strong sheet-like non-metallic materials with a thickness of less than 2mm. The main technical parameters of the instrument conform to the relevant regulations of ISO2493 "Determination of Stiffness of Paper and Cardboard" and GB/T2679·3 "Determination of Stiffness of Paperboard".
Technical characteristics:
The angle can be arbitrarily set between (1～90)°, and the test time can be arbitrarily set within the specified range (3s～35s). Equipped with automatic zero adjustment test function, it is the first fully automatic stiffness tester with 5.7in LCD display curve in China. It can display stiffness and time curve in real time and the operation is simple and convenient. This instrument has the functions of testing, displaying, memory, statistics and printing of various parameters included in the standard, and provides scientific data analysis for the detection of cardboard bending stiffness.
