In the reliability verification of industrial products, temperature testing is one of the most fundamental and crucial means. Low-temperature testing equipment is widely used in fields such as electronics, electrical engineering, automobiles, and materials. However, when the testing temperature requirement drops below -100℃, traditional low-temperature test chambers are no longer competent. At this point, the cryogenic test chamber becomes the ideal choice for simulating extremely cold environments.
This article will analyze the key differences between the cryogenic test chamber and the ordinary low-temperature test chamber, and introduce the LIB cryogenic test equipment solution.
Ordinary low-temperature test chambers are usually suitable for simulating the storage, transportation or usage performance of products in cold environments. Its typical temperature range is:
-20℃, -40℃, -60℃, and some can reach -70℃
Applicable objects include
Consumer electronics, auto parts, plastic materials, LED lighting, etc
The main features of this type of equipment:
Refrigeration is carried out by single-stage or double-stage compressors
The temperature and humidity can be programmed and controlled
Low cost, compact structure and simple operation
The Cryogenic chamber is a dedicated device for ultra-low temperature testing, with a temperature range typically from -100℃ to -150℃. It is mainly used to simulate extreme environments, such as:
Aerospace equipment
Superconducting materials, special alloys
Freezing components in medical devices
Research on extremely cold physical phenomena by scientific research institutions
To cope with extremely low temperatures, the Cryogenic equipment has the following characteristics:
Use a cascade refrigeration system
Reinforced insulation structure to prevent frosting or cold Bridges
III. Comparison of Core Differences
Feature | Standard Low Temperature Chamber | Cryogenic Chamber |
Temperature Range | -20°C ~ -70°C | -100°C ~ -150°C or lower |
Suitable For | General electronics, automotive plastics | Advanced alloys, aerospace materials |
Cooling Method | Single or dual-stage compressor | Cascade system |
Structural Requirements | Standard insulation | Enhanced insulation and anti-frost design |
Cost | Medium to low | Higher, due to technical complexity |
The cryogenic test chamber not only has a lower temperature, but more importantly, it can achieve stability, safety and long-term operation capability at extremely low temperatures.
LIB offers multiple standard models of cryogenic test chambers.

Support for customization: The size of the workroom and the position of the openings can be customized according to the size of the customer's samples and the testing standards
When choosing equipment, it is recommended to make judgments from the following dimensions:
Test temperature requirement: If the test temperature is below -70℃, it is recommended to choose cryogenic equipment
Product attributes: Whether it is made of special materials, high-reliability parts or used in extreme environments
Budget and performance matching: For general tests, choose a regular low-temperature chamber; It is recommended to invest in cryogenic chambers for scientific research and high-end manufacturing
Recommended suggestions:
If the test object is a common electronic device or plastic part, a common low-temperature test chamber can meet the requirements. If the test task involves aerospace materials, bioengineering or special alloys, the LIB cryogenic chamber will be a more reliable choice.
The Cryogenic chamber is not a "colder" ordinary test chamber, but a professional system designed to address the challenges of extreme temperatures. Its core advantages lie in temperature accuracy, safety performance and structural reliability under extremely cold conditions.
