Applications
The CanNeed-PLT-100 Glass Bottle Stress Tester is a precision instrument designed for the food & beverage and glass manufacturing industries to identify structural stress in containers. By detecting internal stress, this tester prevents bottle breakage during high-temperature sterilisation and filling, ensuring production line efficiency and quality control. It is essential for incoming material inspections and process optimisation, fully compliant with GB12415-1996 and GB4545-2007 standards.
Advantages
1) Supports both qualitative and quantitative stress analysis.
2) High-precision digital display for repeatable, objective results.
3) Versatile design accommodates various bottle geometries up to 150mm diameter.
4) Includes a calibration certificate for immediate quality assurance compliance.
5) High-quality polariser with ≥99% polarisation degree for clear stress visualisation.
