Shortening the test evaluation time
Fast heating and cooling times greatly reduce transition time to the set temperature.This can significantly reduce the time for daily test evaluation.
Support for test evaluation in an energized state
Displays and automotive PCUs generate large amounts of heat during durability testing, requiring equipment capable of handling thermal loads.The "Excellent" type, designed to support high thermal loads, can safely and stably conduct test evaluations even when the specimens generate heat at "1000 W at 85℃/85% RH and 2000 W at -40℃."

Quicker Evaluation Testing
The temperature rises and drops quickly, so a drastically shorter time is required to transition to the set temperature. This system reduced testing time by 50% compared to the basic type (low-temperature type).
