HS-NPY Paper Mullen Burst Tester
HS-NPY Paper Mullen Burst Tester
Introduction
Mullen burst tester is the basic instrument for testing the anti-bursting degree of paper and cardboard. It conforms to the standards of ISO2758 Paper- Determination of bursting strength, ISO2759 Board- Determination of bursting strength and GB1539 (method for testing cardboard bursting strength). It uses high precision sensors. With data processing, the data can be directly obtained , and can automatically reset.It has the advantage of easy operation, easy adjustment, stable performance,which make it become the essential instrument for papermaking ,packing, inspection and research.
Standard
ISO2759 GB/T1539 ISO2758 GB/T454
Main Features
1Micro-computer control, use hydraulic oil as the driving force to break the specimen.
2.When the specimen is broken, it stores the maximum automatically
3.Automatic measurements, statistics, print the test results, and has data storage function
4. Micro-printer, high print speed, low failure;
5.Mechanical and electrical integration of modern design, compact structure, excellent appearance, easy maintenance
