Food high and low temperature damp and heat test, three-box stationary hot and cold shock test chamber
Hot and cold shock testing machine stress screening type
Two product uses
Food high and low temperature damp and heat test, three box stationary Thermal shock test chamber
In order to simulate the temperature conditions encountered by different electronic components in the actual use environment, changing the environmental temperature difference range and rapid temperature rise and fall changes can provide a more stringent testing environment, shorten the test time, and reduce the test cost. , but it must be noted that it may have additional effects on material testing and produce destructive tests in non-use conditions. It is necessary to grasp that the test conditions are marked as or that the temperature cycle can control the slope of the temperature shock while the failure mechanism remains unaffected.
