Thermal Shock Chamber
The KTS series of the thermal shock chamber meets all of the major international test standards such as MIL-883H, MIL-202G -107G, JESD22-A104D, IEC 60068-2-14, JASO D014-4, EIAJ ED-2531A and JIS C 60068-2-14.
The KTS series of the thermal shock chamber meets all of the major international test standards such as MIL-883H, MIL-202G -107G, JESD22-A104D, IEC 60068-2-14, JASO D014-4, EIAJ ED-2531A and JIS C 60068-2-14.
The thermal shock chamber has two zones namely the hot zone and the cold zone. The specimen is kept on the test basket, which is transferred between the hot & cold zones through a motorized system connected by a screw rod. It is primarily used to study the impact of the rapid change of temperature on the specimen. In real world scenarios, such rapid change in temperature causes cracking of the material, the mechanical failures and permanent change in electrical performance. It is therefore important to study and analyse such failures to design a better product in order to withstand such changing environmental conditions.
CME’s thermal shock chamber has recently undergone a series of technology upgrades to reduce the overall test time and to shorten the temperature recovery time while maintaining high uniformity. The result thus obtained shows consistent accuracy in temperature recovery and uniformity across multiple test cycles thereby improving the test reproducibility and reliability characteristics of the chamber. Inside the chamber, the hot and cold zones are sealed with specially designed gaskets to minimize leakage between the two zones. The Specially designed test basket of low thermal mass with a powerful temperature-conditioning unit enables the chamber to achieve faster recovery rates.
Thermal shock chamber can also be customized as per the test requirements.
