Product Description

Introduction

Pneumatic 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
