‌Operation Challenges and Safety Guidelines for Rain Test Chambers‌

A rain test chamber (also known as a waterproof testing device or box-type rain testing system) is a core tool for testing the sealability of electronic and electrical product, home appliance, and lighting equipment enclosures. It verifies the functional reliability of products in humid environments by simulating natural rainfall, water seepage, splashing, and other environmental conditions.

Rain test chambers are used to evaluate the waterproofing parameters and performance of automotive components, low-voltage electrical enclosures, and other products. These devices simulate relevant environmental conditions for testing.
