Cometech QC-121D2 Box Compression Tester (BCT) | 20 kN / 50 kN, Fixed or U‑Joint Platen, ISO 12048 / ASTM D642
- Tests compression strength of large packaging materials (cartons, foam, styrofoam) for logistics and warehouse management decisions.
- Multiple sensing points (3-point force measurement) for results closer to real loading conditions.
- Upper compression platen switches between fixed parallel platen and self‑aligning U‑joint platen to match sample surface conditions.
- 7-inch color touch controller shows real-time curve graphs and key results; USB export supported, optional PC software available.
- Conforms to ISO 12048, ISO 2872, ASTM D4169, TAPPI T804, ASTM D642, and other listed packaging standards.

Overview
Cometech QC-121D2 Box Compression Tester is used to evaluate the compression strength and deformation behavior of large packaging materials such as cartons, foam, and styrofoam.
It simulates how shipping boxes react under large force, which is a key test for logistics, warehousing, and packaging validation.
The platform includes multiple sensing points (3-point force measurement) and provides a choice of fixed or U‑joint (self‑aligning) upper platen to improve realism and repeatability across different box surfaces.
