The rapid temperature change test chamber, also known as the temperature cycle test chamber or environmental stress screening (ESS) test chamber, is suitable for environmental stress screening tests. By screening products for environmental stress, it accelerates the discovery of design defects in products and improves product reliability.
lWide temperature range: large-capacity test area.
lTemperature control of test sample: It is available to purchase the test temperature control function.
lNovel design: The design is more case-specific and practical.
