Alternating Low/high Temperature& Humidity test chamber - SGDWJS

Alternating Low/high Temperature& Humidity test chamber

This product is suitable for high/low temperature changes adaptability tests for Electrical, Instruments, Meters and other products, spare parts and materials in stock, transit and use in complex 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~+150C, -70~+150C, -85~+150C etc.

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

2. Chamber humidity control technique

By special structure design of chamber with imported high quality temperature, humidity sensor and control meter, it is sure to keep precise controlling of chamber temperature and humidity, and easy to satisfy regular temperature mistakes controlling of test, meanwhile as requested, we can provide more exactly precise controlling.

3. Control system

Auto and simple operation is the trend of controlling system design, user can spend more time on research of testing result.

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

4. Process

By following high standard of process, our products is up to international standard from outside to quality of parts

5. Regular product technique data
