It complies with relevant standards and adopts pneumatic clamping of specimens and LCD display. It is suitable for measuring the bursting strength of cardboard, corrugated cardboard and other sheet materials.

Main Features
  • After the cardboard is crushed, it will automatically stop and return to the initial position;
  • Fully automatic one-button operation;
  • Can store 50 sets of data at the same time;
  • Equipped with micro-printing, which can print test results;
  • Equipped with emergency stop button to improve operation safety;
  • Equipped with air pressure gauge to monitor pressure at any time;
  • High-definition LCD screen display.
  • Change the traditional glycerin + water method and use silicone oil instead. The machine will not rust easily and extend the life of the machine.
