For environmental testing equipment like constant temperature and humidity test chambers, various factors can affect their operation during use.

A thermal shock test chamber is a device that can rapidly switch between high and low temperatures. It simulates the extreme temperature changes that products may encounter during transportation, storage, and use.

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.
