Note: Extended‑stroke QC‑526D2 models share the same maximum capacity but offer a 1200 mm stroke and taller frame; choose the configuration that matches your specimen length requirements.
Features & Functions
- Large test space and long stroke make the QC‑526D2 suitable for oversized components, long specimens and fixtures with significant height.
- D2 controller with high‑resolution force and displacement acquisition and real‑time display of curves when used with optional display panel or PC software.
- Support for tensile, compression, bending and peel testing with appropriate grips and fixtures, enabling a broad range of mechanical tests on one platform.
- Automatic loadcell recognition and calibration parameters stored in the loadcell chip (D‑series feature), helping speed up loadcell changes.
- Machine protection features such as over‑travel, overload, time‑limit and upper/lower limit switches, plus emergency stop.
Configuration & Options
- Standard vs Extended stroke: choose 800 mm stroke (standard QC‑526D2) or 1200 mm stroke (extended version) depending on specimen length.
- D2 software (Windows): supports tensile, compression, bending and peel tests with multi‑language UI, unit switching, multi‑curve display and comprehensive data analysis.
- Optional display panel: stand‑alone 7‑inch touch screen for production‑line operation, USB export and on‑board test condition memory (D2 controller accessory).
- Grips & fixtures: compatible with Cometech fixtures such as fabric/rubber/webbing tensile grips, compression platens, puncture and double‑sided adjustable grips.
- Loadcells: Cometech grade A/B loadcells with built‑in memory chips; recommended safe overload 140% (Grade A) / 120% (Grade B) and operating range 2–100% of capacity.
