Description
Digital Bursting Strength Tester (BST-952)
The Maxwell Digital Bursting Strength Tester (Model BST-952) is designed for determining the bursting strength of paper, paperboard, packaging materials, corrugated materials, textiles and other flexible sheet specimens
The tester applies hydraulic pressure to a clamped test specimen through a flexible diaphragm. Pressure is progressively increased until the specimen bursts. The maximum pressure required to rupture the specimen is measured and displayed on the digital pressure indicator
Its digital display provides clear and convenient pressure measurement, making the instrument suitable for quality control laboratories, paper and packaging industries, textile laboratories, manufacturing units, research laboratories and testing facilities
The robust construction and simple operating arrangement make the tester suitable for routine laboratory testing and production quality control
Key Features
