0.01mN Lab Testing Equipment Cardboard Bending Stiffness Tester

Cardboard Bending Stiffness Tester

Product Introduction

Stiffness tester is a multi-functional intelligent computerized stiffness tester, 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). With automatic zero test function, it is the first domestic fully automatic stiffness tester that uses a color touch screen as a man-machine interface to display stiffness and time curves in real time. The touch screen is simple and convenient to operate.
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 the bending stiffness of cardboard. The test result is exactly the same as the Taber method and the electronic method. The test result is calculated by the computer intelligently. Two test units are available: mN or mN.m.

Product Features

After the test is completed, return to the starting position at high speed, and the return speed can be set between (1～12);
7.5° and 15° stiffness test (any setting between (1～90)°);
The test time can be set at any number between (3～30)s;
The test angle change is automatically controlled by the motor, which improves the measurement efficiency and reduces the human influence;
It can test 6 kinds of bending lengths: 50mm, 25mm, 20mm, 15mm, 10mm, 5mm (±0.5 mm);
With automatic zero adjustment function, there is no need to manually check the sample before testing;
With measurement statistics, printing and other functions, the measurement time can be set;
The man-machine interface adopts a color touch screen, Chinese and English operating systems, and can communicate with the upper computer software (purchased separately).
