A dynamic mechanical analyzer (DMA) with an extended force range — for soft and stiff samples, with fast recording of modulus changes.
| Deformation modes | Tension, single/dual cantilever, 3-point bending, shear, film-shear, compression |
|---|---|
| Maximum force | 20 N |
| Force resolution | 5×10⁻⁶ N |
| Modulus | 10³ to 10¹³·&sup5; Pa |
| Measurement mode | Dynamic measurements: sinusoidal wave / synthesis wave mode; static measurements: program stress control / program strain control |
| Frequency | Sinusoidal wave: 0,01-200 Hz (up to 20 frequencies simultaneously) · synthesis wave: 5 frequencies simultaneously |
| Temperature range | LN2 cooling: -150 to 600°C · electric gas cooling: -100 to 600°C · air cooling: room temperature to 600°C |
| Cooling system | 3 options — air, liquid nitrogen (LN2), or electric gas cooling. Electric cooling runs on electricity alone, with no external resources; the LN2 platform reduces nitrogen consumption by up to 30% (up to 11 cycles from -125 to 25°C with a 30L Dewar) |
| Sample monitoring | Real View®-ready (option) — a real-time recording of the sample correlated with the measurement curve, including color-change monitoring; the recording can be played back later. Real View (model RV-1DMA) confirmed compatible — “DMA7100” is the older name for this instrument, NEXTA DMA200 is the current model name with the same camera |
| Drive shaft | Spring-mounted, no compressed air required |
| Sensor | LVDT |
| Data reliability verification | Lissajous monitor function — stress/strain relationship verification in real time or after the measurement is complete |
| Software | NEXTA TA — “Guidance Mode” with step-by-step instructions for less experienced users; switch to standard operating mode with full parameter access for advanced users; master curve (TTS) and activation energy calculation included as standard |
| Standards compliance | ISO 6721-11, ASTM D7028-07, IPC 2.4.24.2, JIS K7095, and others, built into the software |
| Data entry automation | Mass Upload Template (CSV import of up to 5.000 sample/condition ID codes), entry via barcode scanning |
| Dimensions | 440 (W) x 630 (D) x 757 (H) mm (without handle) |
