This product is suitable for high/low temperature adaptability tests for Electric, Electronic Instruments, meters and other products, spare parts and materials, in stock, transport and using in high/low temperature environment.

Features:

1. Refrigeration Technique

Together with French "TECUMSEH"/ Germany "COPELAND" Expert of refrigeration, we designed and developed refrigeration plan to keep longer refrigeration and to be according to environment protection.

By regular refrigeration technique, it is easy to satisfy different grade test temperature request, such as -20~+150C, -40~+150 C, -70~+150 C, -85~+150 Cetc.

By liquid Nitrogen refrigeration technique, we can satisfy -180 ~+150 C.

2. Chamber humidity controlling technique

Special structure design of chamber, with high quality import temperature, humidity sensor and controlling meter, can be sure of precise of temperature and humidity, it makes easy to control test temperature deviation, and also we can enhance the precise controlling by your request.

3. Control System

Operation automatically, simply is the tendency of our control system design, by this you could spend much more time in test result research.

4. Process

By following international standard, our products get up to international quality.

5. Regular Technical data

Temp. Fluctuation: +/-0.5C(As request it can be 0.1C)
