Alternating Low/High Temperature&Humidity Test Chamber

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

Features:

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~+150degrees, -40~+150degrees,  -60~+150degrees,   -70~+150degrees  etc.

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

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.

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 of testing result.

By many steps program controlling, we can satisfy different complex testing requests.

Process

Following international standard, our products get up to international quality.
