This instrument is a corrugated cardboard bending stiffness testing instrument designed and developed by our company according to the four-point loading method, which is suitable for all kinds of corrugated cardboard and cardboard. The higher bending stiffness makes the cardboard have a certain degree of rigidity and strength, and improves the ability of the carton to resist bulging, so as to improve the degree of protection of the contents.
Product Features
Closed-loop servo stepping motor, ball screw and three guide shafts provide stable and accurate transmission.
Using stepping motor, low noise and precise control.
A 10-inch color LCD touch screen is used to display the stretching curve in real time.
The ARM processor and 24-bit analog-to-digital converter improve the response speed of the instrument and ensure the real-time performance of the measurement.
Added a data saving function for sudden power failure, the data before the power failure is retained after the power is turned on and the test can be continued.
Features of automatic reset, data memory, overload protection and fault self-diagnosis.
Cooperate with computer software for communication (purchased separately).
