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.

● 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.
● Cotex-M4 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.
● Test data can be exported to USB flash drive.
● The system and screen software can be upgraded through the network or USB flash drive.
● Supports a variety of communication methods, online software (purchased separately) can be WIFI or USB communication.
● Test data can be uploaded to cloud server, and paper test data can be monitored in real time with QMS paper quality management system (purchased separately).
