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).
