Product Description
Bursting Strength Tester (Analog Type)
A Bursting Strength Tester (Analog) is a laboratory instrument used to measure the bursting strength of materials like paper, paperboard, corrugated board, fabric, and packaging materials. It evaluates the materials resistance to rupture when subjected to uniform pressure.
In the analog version, results are displayed on a mechanical dial gauge rather than digitally.

Working Principle
1. A sample is clamped over a rubber diaphragm.
2. Hydraulic pressure is applied gradually beneath the diaphragm.
3. The diaphragm pushes against the sample until it bursts.
4. The maximum pressure required to burst the sample is read on the analog dial gauge (usually in kg/cm or psi).
