Product Description

Constant Humidity Chamber Manufacturer & Supplier

The constant humidity chamber is an reliable environmental test system that offers exceptional precision in humidity control for a wide range of industrial testing applications. It is specifically designed to create and maintain precise humidity conditions within its insulated stainless steel enclosure, ensuring accurate and consistent test results.

In addition to humidity control, this chamber also features an efficient airflow circulation system. This system ensures that the humidity is evenly distributed across the entire chamber, eliminating any potential variations in test conditions. This guarantees reliable and repeatable test results, making the chamber an indispensable tool for research, development, and quality control processes.

Applications

Constant humidity chambers are used for:

  • Pharma - Conducting drug stability testing in compliance with ICH (International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use) guidelines. The chambers provide a controlled environment for assessing the long-term stability and shelf life of pharmaceutical products under specific humidity conditions, ensuring regulatory compliance and consumer safety.

  • Food - Testing the storage life of various food products under controlled humidity conditions. By simulating different levels of humidity, these chambers enable food manufacturers to evaluate the impact of moisture on product quality, freshness, and shelf life, aiding in the development of optimal storage and packaging solutions.

  • Electronics - Assessing the effects of humidity on electronic components and devices, particularly in terms of corrosion and moisture resistance. Temperature humidity environmental chambers create controlled environments to simulate real-world conditions, allowing manufacturers to validate the reliability and performance of their products under varying humidity levels.

  • Automotive - Evaluating the moisture resistance of automotive parts and components. These chambers provide a controlled setting for subjecting auto parts to specific humidity levels, enabling manufacturers to assess the impact of moisture on materials, coatings, and electronic systems, ensuring the durability and longevity of automotive products.

  • Packaging - Analyzing the performance of packaging materials and containers under high humidity conditions. The chambers facilitate accelerated aging tests and quality assessments of packaging materials, helping manufacturers ensure the integrity and effectiveness of their packaging solutions in humid environments.
