Product reliability is no longer governed solely by design rules and manufacturing precision; it is equally decided by a product’s ability to survive sudden climatic extremes. Among all environmental stressors, rapid temperature change is the single most frequent root-cause of field failures in electronic components, automotive assemblies, and aerospace hardware.

A high-temperature test chamber is an essential instrument for evaluating the reliability of industrial products under extreme heat conditions. It tests various performance metrics of products exposed to high and low-temperature transitions.

The operation of the sand and dust test chamber primarily involves using a fan to blow sand and dust of the required concentration at an appropriate flow rate over the surface of the test sample.
