Product Description
Introduction:
The Multi-function intelligent computer stiffness tester is suitable for measuring the bending stiffness of paper, cardboard and other non-metallic materials with a thickness of less than 2mm.
The test angle of the instrument can be set arbitrarily between (1 90) , and the test time can be set arbitrarily within the specified range (3s 30s). Equipped with an automatic zero test function, it is the first fully automatic stiffness tester in China that uses a color touch screen as a human-machine interface. It displays the stiffness and time curve in real time. The touch screen operation is simple and convenient. This instrument has the functions of parameter testing, display, memory, statistics, and printing, and provides scientific data analysis for cardboard stiffness detection.
