GZ-034 cardboard stiffness tester
The main function:
Microcomputer paper stiffness tester is a multi-functional intelligent computer stiffness tester for measuring the thickness of less than 2mm of paper, cardboard and other non-metallic materials-strength sheet bending stiffness.
Microcomputer paper stiffness tester can be set at an angle between (1 ~ 90) °, test time is arbitrarily set within the predetermined range (3s ~ 35s). With automatic zeroing function test, it is the first launch of the 5.7in LCD automatic stiffness graph analyzer, real-time display simple stiffness and time curve and convenient. This instrument has the parameters of the test criteria included, display, memory, statistics and print functions, cardboard bending stiffness test to provide data and scientific analysis.
