Product Application<\/h3>\n\n\n\n

This chamber is mainly applied for adaptability tests of finished products, components and materials (electronics, electrical appliances, food, automobile parts, rubber & plastics, metal materials, etc.) during storage, transportation and service under alternating high-low temperature and humid-heat environments.
It serves as reliability testing equipment for cold resistance, heat resistance, humidity resistance and dry resistance tests on raw materials and components of electronics, electrical products and plastic products for quality control projects.
It is especially suitable for cyclic high temperature, low temperature and damp resistance tests for optical fibers, LCDs, crystals, inductors, PCBs, batteries, computers, mobile phones, rubber and plastic products.<\/p>\n\n\n\n
