TS Series Two-Zone Thermal Shock Test Chamber

Environmental chamber for evaluating product reliability through rapid transitions between hot and cold temperature zones

A two-zone thermal shock chamber transfers samples between separate hot and cold sections to create immediate temperature changes. This method is essential for uncovering hidden defects, validating product durability, and ensuring components can tolerate rapid thermal stress during use.

Condensing method Air-cooled Water-cooled

For air-cooled models, the stated performance is based on ambient conditions of +25 °C with relative humidity ≤85%, measured with no test specimens inside the chamber. For water-cooled models, performance is based on ambient temperature between +15 °C and +35 °C, relative humidity ≤85%, and cooling water temperature ≤+28 °C, also measured without test specimens inside.

The main difference is in how the temperature changes are applied to the sample. Thermal shock chambers create an immediate and extreme transition from hot to cold without any gradual ramp. This sudden exposure helps reveal weaknesses that may not appear under slower transitions. In comparison, temperature and humidity chambers and rapid-rate thermal cycle chambers change the temperature at controlled rates over time, so there is always a transition period instead of an instant shift.

Three zone chambers are suitable for samples that are sensitive to vibration or require testing while powered, such as precision electronics or automotive components. They also handle frequent, continuous shock cycles more effectively. Two zone chambers are designed for small samples like chips or plastic parts that are less affected by vibration and where quick thermal shock testing is the priority.
