Digital mullen bursting strength machine for paper cardboard 

It is the basic instrument for testing the anti-bursting degree of paper or cardboard. For cardboard: It conforms to the standards of ISO2759 (standard testing for cardboard bursting strength) and GB1539 (method for testing cardboard bursting strength). For paper: It conforms to the standards of ISO2758. It adopts signal transmitting press. When the specimen is burst, the tester stores the maximum of bursting strength automatically.

Characters:

1. Micro-computer control, use hydraulic oil as the driving force to break the specimen.

2. When the specimen is broken, it stores the maximum and reset automatically.

3. LCD displays, the unit of kgf/cm2, psi and kPa  in option.

4. It adopts signal transmitting press

5. ISO 2759 and ISO 2758.

6. running joint is made of brass so that prolong its life-span.
