QM930D Thermal-Gradient Tester

The QM930D builds a temperature gradient across 5 independent platens with pressure and time control to quickly determine film heat-seal state and the optimal sealing process window. A removable head adapter prevents misalignment when changing heating blocks, ensuring continuous-test accuracy.

One test yields the entire heat-seal temperature range - from cold seal to hot seal - quickly finding optimal sealing conditions.

Key Product Features

A 5-zone thermal-gradient platform - 5 independent platens build a temperature gradient, covering the entire heat-seal temperature window in one test.

5-Zone Independent Heating

Five independently settable heated platens build a continuous temperature gradient, yielding the whole heat-seal window in one test.

Teflon Anti-Stick Bottom Plate

Teflon-coated heated platens prevent sticking; samples release cleanly from the bed, saving cleaning time.

Color Touchscreen Control

Color touchscreen operation; temperature/pressure/time parameters set intuitively; test methods can be stored and recalled.

Removable Head Adapter

The removable head adapter prevents misalignment when changing heating blocks, keeping pressure distribution uniform in continuous use.

High-Precision Flatness Maintenance

A base anti-sway structure with auto-lock system maintains high-precision flatness during testing for stable, reliable data.
