Introduction
Rapid temperature change test chamber is suitable for electronic components, automotive parts and other materials, such as safety performance testing to provide reliability tests, product screening tests, etc., while the test through this equipment can improve the reliability of the product and the quality control of the product. When the material constituting the various components of the product thermal match is poor, or components of the internal stress is greater, the temperature cycle test can trigger the product by the mechanical structure of the defects of the deterioration of the failure of the product.
Safety & Protections
Power supply undervoltage, over-voltage, missing phase, phase sequence error protection; 3 kinds of overtemperature protection; Heater short circuit protection; Compressor overpressure/ overload/ lack of oil protection; Humidifier fault protection; Blower motor overload/overheat protection; Panel over-current protection, earth leakage protection; cooling water shortage protection.
Application
It is used for electronics, electrical products and machine parts to do cold-resistant test, rapid changes in temperature or gradient test and especially used for electronics, electrical products to do environmental stress screening test.
