Tescor's Thermal Shock Chamber reveals the impact of rapid temperature change on test specimens as they move through hot and cold zones. Through the use of a test basket that is transferred between hot and cold zones by a motorized system connected by a screw rod, rapid temperature changes expose product design failures of the test specimen, including cracking of the material, mechanical failures, and permanent change in electrical performance. The Thermal Shock chamber shows consistent accuracy in temperature recovery and uniformity across multiple test cycles, providing test reproducibility and reliability characteristics of the chamber. The hot and cold zones are sealed with specially designed gaskets to minimize leakage between the two zones. The test basket features low thermal mass with a powerful temperature-conditioning unit, enabling the chamber to achieve faster recovery rates. The Thermal Shock chamber meets all major international test standards.
