Two Zone High Low Temperature Thermal Shock Chamber Shock Simulate Test Chamber

1.Two-Zone High and Low Temperature Shock Simulate Test Chamber that subjects a product to alternating extremes of high and low temperatures in order to observe changes in product characteristics and failure occurrence caused by different materials and their thermal expansion coefficients. Thermal shock chamber utilizes controlled areas for hot, ambient and cold temperatures. The product is moved from ambient to hot or ambient to cold zones. The chamber can be programmed to include a dwell period in the ambient zone if desired.It is applicable to metals, plastic, rubber, electronics amongst other materials. The test result can be Used as a reference or basis for product improvement.
