With the continuous tightening of ingress-protection requirements in automotive electronics, low-voltage power distribution and photovoltaic industries, repeatable, quantifiable and traceable artificial-rain testing has replaced the traditional “splash-and-inspect” approach and become the core means of verifying sealing performance.

Many users often overlook seemingly minor details when operating a high and low temperature alternating test chamber. However, these small oversights can lead to unreliable test results or even safety hazards.

High and low temperature humidity test chambers require electricity to operate, which inevitably leads to energy consumption. Saving electricity not only reduces energy waste but also lowers the operational costs of the equipment.

Although both thermal-shock and steady-state temperature/humidity tests fall under the umbrella of “weathering verification”, they differ fundamentally in physical modelling, control logic and safety strategy.

The compressor is a critical component of a low-temperature test chamber.
