  • Overview of Equipment
  • Features
Uniformity, reproducibility
Wind simulation allows achieving minimum temperature variations of the specimen, for accurate and quick temperature changes. Specimen temperature ramp rate is 15°C/min, air temperature ramp rate is 23°C/min.
Greater temperature ramp control

High precision of the specimen temperature control achieved thanks to a sensor for temperature specimen measurement, and the embedded high-speed controller.

In addition:

  • refrigeration capacities increased at low temperatures,
  • minimization of the difference between test area and specimen temperatures,
  • airflow speed uniformity,

lead to excellent temperature ramp control.

Selection of the temperature control mode

Two temperature control modes are available:

  • A specimen temperature control mode meeting ramp rate conditions of JEDEC standard (15°C/min.)
  • An air temperature control mode for temperature cycle tests.
Free access
Cable ports are equipped on both left and right side, to ease specimen access and wiring.

Specimen temperature ramp control (Example)
