High and Low Temperature Thermal Shock Chamber
HLST-500D
-
The specimen is placed in test chamber specimen which cannot be placed in high temperature chamber or low temperature chamber. High temperature chamber pre-heats the air and low temperature air chamber pre-cools the air. When doing the test of temperature changing from high to low, the low temperature chamber will blow the pre-cooled air to the test chamber. Then, the air in test chamber will reach your target temperature in several minutes (“recover time”). When doing the test of temperature changing from low to high, the high temperature chamber will blow the pre-heated air to the test chamber. Then the air in test chamber will reach your target temperature within the recover time.

Liquid-To-Liquid Thermal Shock Chambers
-
Purchasing a liquid thermal shock chamber needs close consideration of the long term operating costs. The specialized liquids used can easily evaporate, causing the loss of thousands of dollars of fluid per year, if not properly contained. Liquid-to-liquid thermal shock testing is typically conducted to apply very strong, repetitive thermal stress to test pieces. It can model a product's ability to withstand thermally-induced size changes, crack resistance, hermetic integrity, and changes in electrical properties. This form of testing provides a very rapid temperature shock recovery of conditions, and it can significantly reduce testing time by requiring shorter soaks and less cycles.

We provide a large selection of thermal shock chambers to accommodate various types of product testing. Thermal Shock Chambers perform tailored environmental stress screening of component and board electronic assemblies. Our unique chamber design transfers product between two extreme temperature-controlled chambers, passing equal volumes of high velocity conditioned air over the product and resulting in rapid product temperature changes. The induced thermal stresses can reveal hidden manufacturing defects in electronic sub-assemblies and other components by the expansion and contraction of critical parts.

General Purpose Heat Flow Meters

Thermal conductivity defines a material’s ability to transfer heat. A precise and accurate measurement is critical for any process or material experiencing large or fast temperature gradients, or for which the tolerance for temperature changes is exacting. Accurate values are essential for modeling and managing heat, whether the component of interest is called on to insulate, conduct, or simply withstand temperature changes. Information about these properties are routinely used in heat transfer models of all complexities. Thermophysical property measurements also reflect important information about material composition, purity and structure, as well as secondary performance characteristics such as tolerance to thermal shock.
