Product Overview


The Temperature and Humidity Test Chamber is designed to simulate various environmental conditions such as cold, heat, humidity, and dryness, ensuring reliable performance testing for products under extreme climates. It is widely used for electronic components, electrical appliances, plastic materials, and other industrial products, helping manufacturers evaluate product durability and reliability during storage and transportation.

This chamber provides precise temperature and humidity control, enabling users to perform stability, aging, and cyclic tests with high accuracy. Built with advanced insulation and intelligent control systems, it ensures consistent and repeatable test results.

The equipment fully complies with international standards including IEC60068-2-1 (Cold Test), IEC60068-2-2 (Dry Heat Test), IEC60068-2-78 (Damp Heat, Steady State), and IEC60068-2-30 (Damp Heat, Cyclic Test) — making it an ideal solution for environmental reliability testing in R&D and quality assurance laboratories.
