A low-temperature test chamber is designed for low-temperature testing, but can it also perform humidity tests on specimens? When purchasing this type of testing equipment, can users expect it to handle both temperature and humidity tests?

With the continuous updating of GB/T 4208-2017, IEC 60529:2013, MIL-STD-810H and other domestic and international protection-class standards, “rain testing” has evolved from a simple “water-proof check” into a systematic evaluation covering sealing reliability, material weatherability, structural integrity, electronic compatibility and more.

High-low temperature test chambers are precision instruments that must be operated strictly by trained personnel following standard procedures and subjected to regular preventive maintenance. Any operational error or neglected upkeep can trigger a variety of faults, delaying test schedules. The equipment integrates refrigeration, heating, humidification, electrical control and other subsystems. Effective troubleshooting therefore requires a holistic “whole-machine mindset” to pinpoint and solve problems quickly.

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.

Previously, we have discussed many technical aspects of temperature cycling test chambers. Today, we will share methods for detecting leaks in these chambers. Specifically, there are four main approaches to check for leaks.
