Product Overview
The 960L Temperature Humidity Chamber is a high-performance
environmental testing system engineered to recreate real-world
climatic conditions with exceptional accuracy. Designed to simulate
extreme temperatures, rapid temperature changes, and controlled
humidity levels, this chamber provides a reliable platform for
evaluating the durability and stability of a wide range of products
— including electronics, electrical appliances, plastics,
automotive parts, and industrial components.
With its spacious 960-liter capacity, precise control system, and
programmable test cycles, the chamber enables manufacturers to
expose samples to harsh environmental stresses such as heat, cold,
moisture, and dryness. This helps uncover potential weaknesses
early, optimize product design, and ensure long-term performance
throughout storage, transportation, and actual field use.
Built for modern laboratories and production lines, the 960L
Temperature Humidity Chamber is an essential piece of equipment for
reliability testing, quality assurance, and compliance with
international standards — delivering consistent, repeatable, and
trustworthy test results every time.
