- 7‑inch color touch screen with real‑time display of force–displacement or force–time graphs, plus test information and limits.
- Basic test methods: tensile, compression, peeling and bending (fixture‑dependent).
- Automatic specimen information handling, test condition memory and one‑click start for repetitive QC routines.
- Metric and imperial units, stroke/force/time‑limit protection, breakpoint stop and automatic return after test.
- Storage of up to 50 data sets and USB export of raw data for further analysis.
Configuration & Options
- D2 software (Windows 7 SP1 or above) for tensile, compression, bending and peel tests, with data sampling up to 1200 Hz and flexible graph/table layouts.
- Software supports multi‑language UI, metric/imperial switching, customizable X–Y axes (force, elongation, displacement, time, stress, strain) and statistical analysis with user‑defined formulas.
- Optional compact printer for immediate stand‑alone reports (max force, max displacement, etc.).
- Wide range of grips and fixtures: coefficient of friction tables, wire tensile grips, 90° peeling grips, rubber tensile grips, plastic film puncture fixtures and top‑load grips.
- Loadcells with internal memory chips storing calibration parameters, available in multiple capacities and grades (A/B) with 140% / 120% safe overload, easily replaceable with standard tools.
