Cometech QC-121M1F Carton / Box Compression Tester (BCT) | ISO 12048, ASTM D642, 20 kN / 50 kN
- Measures compression capacity and deformation of large packaging materials (cartons, foams, styrofoam) for logistics and warehouse management.
- 3-point force measurement improves force sensing accuracy and stability.
- Upper platen switchable: fixed parallel platen or self‑aligning U‑joint platen for more realistic contact on imperfect surfaces.
- Stand-alone 7-inch TFT touch controller with curve display, USB export, and multi-stop conditions; optional PC software via TCP/IP.
- Software supports multiple patterns including basic compression, constant load compression, and dynamic load compression (as listed).

Overview
Cometech QC-121M1F Carton (Box) Compression Tester evaluates the compression strength and deformation behavior of large packaging materials such as cartons, foam, and styrofoam.
It simulates how shipping boxes behave under large force, a key parameter for packaging validation, transport safety, and warehouse stacking decisions.
The system uses evenly distributed sensing (3-point force measurement) and offers either a fixed or U‑joint (self‑aligning) upper platen to improve measurement realism and repeatability.
